Sad Mac 000000 reply: This is a 3.2.3 based platform, with valid ROM and disk images. It behaves correctly at rejecting images, but immediately throws a Sad Mac with the above error when attempting to load a valid disk image. If you do not know this bug, I might report it downstream to the guy overseeing the builds.

You didn't answer my questions, but I would guess that you are using the Android port, which I'm not involved with.

I suggest you try using your disk image with a version of Mini vMac that I provide. If it still doesn't work, then I can try to help you. But if it works fine, then there may be a problem with the port.

Do you know anything about your emulator throwing the Sad Mac error 000000?

No. I'd need more details to be able to help you. Are you using the standard variation of Mini vMac I provide (in which case, for which platform?), a custom variation from the Variations Service (which variation number?), or a version you compiled yourself (with what options)? In what circumstances do you see this error?

Hi, I'm hoping to use min vmac to open my old mindwrite documents. I have the mini vmac emulator and mindwrite 2.1 up and running, but my experience so far is that I cannot import the old mindwrite files to the mini vmac ecosystem, though I gather from the testimonials page that this must be possible. How do I do this? And then how would I export them again in another format, readable by contemporary word processing programs? Please note that I cannot currently open any of the mindwrite files using any contemporary WP programs, which is why I am attempting to use min vmac. Thanks in advance for your help.

Dan Lawrence

I happen to own MindWrite 2.1, though I haven't looked at it much before (bought cheap secondhand, among many others).

As far as I can tell, though MindWrite does write a little bit of information to the resource fork of a file, it doesn't really require that information. So you can use ImportFl to import MindWrite files. Then you just have to set the file type to "OUTL" so that MindWrite can open it. (You can also set the file creator to "PWRI" so that it will have the proper icon.) You can do this with Finder Info or Creator Changer (or many other possibilities).

To export MindWrite files, it does have a "Save As" command that can write plain text files, and then you can use ExportFl. It also can export to other file formats such as Mac Write and some early versions of Microsoft Word. If you write a Word file, and then open it with a not quite so old version of Word (perhaps version 5, which can run in Mini vMac), and save it again, you could get a file readable by the current Microsoft Word, that might preserve some formatting from the original.

Though converting documents to a modern format is useful in some circumstances, in my opinion it does not help to preserve them. Each time the document has to be updated for the curent software, it will get modified and munged a little more. Instead, using an emulator such as Mini vMac allows you to see the original document exactly in its original form. And it is far less work to maintain one emulator than for everyone to continually update multiple documents to current formats.

The disk images section is interesting, but does not cover a fairly simple situation:

Someone has an older Macintosh, with real floppies and/or a hard disk, and wants to migrate data from them to a Mini vMac-supported image.

Generally-speaking, the most flexible Macs will be Powerbooks with FDHD floppy drives (400, 800, 1.44 compatible) and PCMCIA slots (can easily use Compact Flash), or early G3 Powerbooks with USB.

With a "real" hardware baseline of System 7.5.5 (say, PB 5300c), what would be the process to prepare/mount a readable image on the operational Mac? For example, do older 7.5.5 compatible disk image include both a resource and data fork, making it difficult to move them from/to a Windows environment?



(Ottawa, ON)

One approach would be to mount one of the blank disk images I provide, on your old Macintosh, using SetFType to make it mountable (as mentioned on the working with disk images page). Once the image is mounted, you can copy files on to it, unmount it, and then transfer the disk image to the computer where you wish to run Mini vMac. (The best way to transfer files to and from your old Macintosh depends on exactly what hardware you have available.)

Another approach would be to use the Disk Copy application on your old Macintosh to create a new disk image, which sounds like what you had in mind. This should work, as long as you make sure to create an uncompressed read/write image. It may create a resource fork, but if I recall correctly, the image can still be used in Mini vMac if this resource fork is lost.

Dear Paul,

First of all thousand thanks for the Mini vMac, a wonderful effort I am very grateful for.

I have a question: I would like to have a variant for the Macintosh Color Classic (or Macintosh Color Classic II). I have the ROM but find no option to generate a Mini vMac app for that Mac. Note, that Mac supports 32,768 colours, but is otherwise very similar to an older Mac such as a Mac Plus. Remember also that QuickTime did since its very beginning always support 8 colours, despite screens being black&white only. This means that much of the older software might suddenly show up in nice colours, although having originally been designed mostly for the b&w Macs in the first place. That is my main motivation for looking for a Color Classic variant of Mini vMac, since I have a few of those applications I would like to run in Mini vMac.

Any thoughts on that?

Thanks for your help and cooperation and once more many, many thanks for Mini vMac.

If I remember correctly, the original Macintosh Quickdraw API has in a few places a limited concept of color, I think mainly intended for printing. But when Color Quickdraw was later created for the Macintosh II, a completely new and different API was created for color. I don't think much software made any use of the original color API. (relevant Wikipedia.)

But a lot of software that was written for somewhat later Macintosh computers and use color was made to also work on older computers with only black and white. So a lot of software that works in the Macintosh Plus emulation of Mini vMac will show color if run in the (incomplete) Macintosh II emulation of Mini vMac.

The Macintosh Color Classic is the same general shape as a Macintosh Plus and targeted for the same market segment. But inside, it is directly evolved from the Macintosh II and uses the same Color Quickdraw seen in a Macintosh II. So to emulate a Macintosh Color Classic in Mini vMac, the first step is to finish the Macintosh II emulation. Which unfortunately is not expected in the foreseeable future. See this earlier question.

Hi, Paul:

What is the status of networking for the Mini vMac project?

Mike Ford's last update on LT for OS X is from 2012. Is there a timetable for inclusion into the main MvM project? Do you know of any other groups that are working on this?

On my Vintage (real) Macs, I tend to focus on networking to enable "modern" devices (no floppies, cds, on the macs, etc) just the network to provide access to flash drives, CDs, etc.

Mike Fort’s LocalTalk emulation is in Mini vMac 3.3 (for OS X only) using the -lt build option, and is available through the Variations Service.

Further to previous note on supporting 32-bit clean ROMs for large RAM support.

It might be easier to target the LCIII ROMs, rather than IIci or IIsi ROMs which will also need NuBus support.

The LCIII can support 256MB RAM, in theory, but not in the hardware. It does support 128MB 72pin SIMMs, that's been demonstrated, but the soldered on 4MB of Bank A can't be upgraded, of course.

Hi, Paul:

The Macintosh II can support 128MB with the Rev.2 ROMs(IIx)and I've found Mini vMac working fine with IIci ROMs. Any chance that Mini vMac can compile for up to 128MB of RAM. I really need it to run some old Mac Productivity apps.

I know about Basilisk, but I find it much slower than Mini vMac, even with a Core2Duo Thinkpad.

Mini vMac can be compiled for more RAM in the Macintosh II emulation, but it doesn't yet work. A Macintosh II ROM is not “32 bit clean” and so will not normally support more than 8M of memory. There is some additional software available that allows more memory, which presumably replaces ROM routines, but it doesn't work in Mini vMac for reasons not yet known.

It is said ( [1] [2] ) that the Macintosh IIx ROM is not 32 bit clean either.

The emulation of the 68000 CPU in Mini vMac uses assembly language on PowerPC and x86-32. There isn’t an assembly language version of 68020 emulation for the Macintosh II, so it is slower, and seems unlikely to be faster than Basilisk II (especially the JIT version).

I love your work on Mini vMac. I first learned about it by the TI nSpire calculator port, and just recently installed on all my computers. I know it's a very aesthetic request, but is there any chance you could put the display in an image of a Macintosh, or if you want to get fancy, put an image browser that would embed the screen in the transparent section of an image? Here's an example of what I mean: https://openclipart.org/image/2400px/svg_to_png/59965/1273636396.png

Would it be possible to make that image the window and put the display screen in the black display in the image?


That doesn't appeal to me at all, but that isn't a reason not to implement this. The point of compile time options (and the Variations Service) is that everyone can have exactly the Mini vMac they want, without making it bloated, large and slow.

The difficulty is actually in drawing the picture. If Mini vMac used operating system routines to draw, say, png format, then that would make Mini vMac less portable. If Mini vMac insteaded included code to draw png, that would be a lot of code, not only making the compiled program larger (which doesn't matter so much for a compile time option), but also it would be a lot of code to understand and maintain.

Speed setting of 2x doesn't seem to be working in the speed control mode...

all other speeds work great, but [control S > 1] doesn't change anything.

A great feature would to be the option to adjust the magnify factor to something other than 2x) ~1.25x for example would scale Mini vMac to the same physical size of an actual classic mac screen on my 24 apple display.

love the project!

I suspect the problem with the 2x speed is that your operating system is intercepting the key. For example, in OS X, Control-<Number> can be used by Mission Control by default. If you go to the System Preferences, select Keyboard, select Shortcuts, then select Mission Control, you can disable this shortcut (for Switch to Desktop 1), or change it to some thing else.

An alternative workaround is to use Control-Shift-1. Mini vMac ignores the shift key, but OS X doesn't and no longer intercepts the key.

Mini vMac can be compiled to use other integer magnification factors with the -mf option. The Variations Service supports this option. But regarding non integer magnification, see this previous question. It's not impossible, but it unavoidably would look very bad.

I've just tried to pull a ROM from my Supermac Spectrum/24 PDQ+ Nubus card in Slot10. slotrom 1.0.3 throws with "There is not enough memory".

Would you know what causes this? I've run it from a share that had gigs free, the desktop with 800mb free and another partition on the mac with 1gb free. It's running on a Quadra 950.

I also tried giving it more RAM (virtual) up to 200mb. I'll be receiving 256mb of real RAM shortly and will try again.

My email is [... email address ...] and my goal is to create a museum of Supermac/Radius ROMs so that we can upgrade the poor things.

When you say “I also tried giving it more RAM (virtual)”, do you mean that you just changed the virtual memory size of the entire computer? Or did you “Get Info” on the SlotRom application icon in the Finder and change the Preferred memory size.

On old Macintosh computers, once it became possible to run multiple programs at once, you still had to manually choose how much memory to give each program.

From your debuglog, it looks like it was trying to allocate 64K, which may not fit into the default 128K memory allocation for SlotRom. I should increase the default Preferred size for SlotRom (while still leaving the Minimum size at 128K.)

Update - April 30 2015 - In SlotRom-1.0.4, I've increased the Preferred memory size.

First, make sure to use the “-ev” option of the build system to request the most recent supported version of Xcode - 4.0 (which is not very recent).

But I'm not sure whether recent Xcode even still supports Carbon, I haven't been following Xcode changes lately. You can instead try the Cocoa port in the 3.4 branch by using “-api cco” in the build system.

Update - June 10, 2015 - I've updated the 3.4 branch to support current Xcode versions. I've verified that compiling the Carbon version doesn't work, you need to compile the Cocoa version. (The Carbon version almost compiles, but as you found, a few routines are now missing from the API for no clear reason, other than that Apple doesn't care.)

So, LSRequiresCarbon is being set to the string "true/". This is surely a typo and was meant to have been the string "true" ("<string>true</string>"), or perhaps the Boolean true ("<true/>"), however according to the Apple documentation, the correct value to use when one wants to enable this key is the string "1" ("<string>1</string>"). If one does not care about supporting OS X versions earlier than 10.2, one can use the Boolean true, but there appears to be no good reason to do so.

Hello again, sorry to bother you with this.

Mini VMac for Linux segfaults when trying to compile a new version using the build system, or to export a file with the ExportFl program. I can reliably reproduce this segfault with both the 32bit and 64bit versions, with vmac running either system 6 or system 7. Host system is Ubuntu Studio 64bit.

Many thanks for any help you could give me on this,

- Éric. (Montréal, Canada)

Thank you for the bug report. I have found a bug that may have caused this.

In the Linux version, when exporting a file, Mini vMac will normally try to save it to a folder named “out” in the application directory (creating the folder if it doesn't exist). If file permissions are set so that Mini vMac can't find or create this folder, it will crash, due to not properly handling errors in the routine “FindOrMakeChild” in the source file “MYOSGLUE.c”.

I'll make a new development source snapshot with this fix. In the mean time, you can work around this problem by changing file permissions on the application directory, or by using the “-d command line option” to tell Mini vMac to use a different directory.

Great idea!!!!

Mini vmac really changed my mind about computers: experiencing the reality of old 68k days... thats awesome.

But i have a question: why is this page so ugly? Sure, it is a experiment, but i think it would be a really good challenge for me to tweak a little bit the Gryphel Project's website, don't you think?

Im looking forward for your response(and, with luck, your aproval!).

Thank you for your offer.

However, a major redesign of the website would inevitably require a lot of my time, which unfortunately isn't available right now. Even if I just accepted a new website that you hand me, to maintain it and add new content would still require learning about modern web technologies, which would take time.

The current design of the website is intended to work on very old web browsers that will run on a Mac Plus. Which is a logical constraint for the Gryphel Project. But it is also just an excuse to avoid spending time chasing current web fashions. Myself, I'm a fan of this school of web design (warning: vulgar), and disregard the bit about it being satire. I'll admit though that for the good of the Gryphel Project, I should consider what is most effective for the intended audience, not just my taste.

By the way, using the original HTML technology, these pages basically just contain the text and a few hints. What it looks like is up to your web browser. Perhaps you could try a different web browser. Or see what preferences there are in the browser you do use, especially default font preferences.

Hi, I sent the bug report about the disks not mounting.

[previous message]

I'm running Mini vMac 32 bit on a Windows 7 Professional 64 bit system. All the Mini vMac version 3.3.3 variations are having this problem. Older versions of Mini vMac are not having this problem. Example version 3.2.3 mounts all six disks just fine.

While experimenting I've discovered something new. Originally I was trying to auto mount disk1.dsk and disk2.dsk and only disk1.dsk was showing up in the finder. I extended that to disk3.dsk and it would not show up in the finder either. So, I tried to mount all six disks. disk1.dsk, disk4.dks, disk5.dsk, and disk6.dsk all auto mount and show up in the finder disk2.dsk and disk3.dsk do not show up in the finder but if I try to manually mount them it says they are in use. Also this does not happen if I try Mini vMac version 3.2.3. It mounts all six disks just fine.

I've also tried booting different Mac OS versions 6.0.8, 6.0.5, 7.5.3 etc... they all have the same problem on version 3.3.3 but not on 3.2.3 too.

This is not just happening with the Mini vMac versions from the Variations Service but I also compiled and built my own versions using lcc-win32. They all have the same problem too.

My email is [... email address ...]


Thanks for the further information.

I'm not seeing this in 64-bit Windows 7 Home Premium N running in VMWare. I'll try this on a real machine later. Also I should try applying all available Windows updates in the virtual machine, it's been some years since I set up that VM.

Since you can build from source, you might try changing MinTicksBetweenInsert in the file SONYEMDV.c, and see if that changes the number of images that are not properly mounted.

Also, if instead of naming disk images "disk1.dsk", "disk2.dsk", etc., you specified images to mount on the command line, do you get the same behavior?

I'm having a problem with the latest builds from the Variations Service. They won't automatically mount more than one disk on startup. disk1.dsk mounts fine and the emulated computer boots up but disk2.dsk, disk3.dsk, etc... don't automatically mount. If I try to open disk2.dsk manually it says the disk is already in use and it won't let me mount it. It's as if it is partially mounting disk2.dsk but it is not showing up in the finder.

It tried building my own variations but they all have the same problem. Is this a bug in the software?

Thanks for the bug report.

I'm not seeing this behavior. What specific variation number(s) have you tried? What operating system are you running it on?

What software is in "disk1.dsk"? Does a fresh install of System Software have the same problem? (Perhaps some 3rd party software could temporarily put a Macintosh into a state where it doesn't accept disk insertions.)

I assume if you rename disk2.dsk to something else, and then launch Mini vMac, it works to manually mount it after booting?

I am currently using mini vmac II on my android rca pro 10 tablet. I would like a version custom built to work on my tablet. I have os 7.5.3 running on it now at 640x480 res. It only has 8,192k Total memory which is too small for my Hypercard apps. My tablet has a quad-core processor and it is android 4.2.2 jelly bean. Can you make me a custom mini vmac with a larger screen and larger Total memory to fit my tablet? I have many roms and os's 1.0 to 9.2.2. I would like to run an os as high as it will run and be stable and dependable. If you can do this for me, I would be very greatful, please let me know. [... email address ...] Thanks, Dale

Sorry, I'm not involved in the Android port of Mini vMac. I don't how to compile a program for Android. Within a year or so I may learn more about it, for my paid work.

Also the incomplete Macintosh II emulation of Mini vMac does not support more than 8M of memory. The Macintosh II ROM is not 32 bit clean, so even a real Mac II will not normally support more than 8M of memory. There is some additional software available that allows more memory, which presumably replaces ROM routines, but it doesn't work in Mini vMac for reasons not yet known.

Taking the fairly unscientific measurement, I'm assuming the Mac Classic is powered by an 8MHz 68000 at around 1.4 MIPS. I guess that fancy Amiga-like custom chips and graphical accelerators don't enter into things too much. I've also completely left things like FastRAM out of the picture as well.

A standard unmodded Atari Falcon with a 16MHz 68030 has 5.76 MIPS, so an uninspiring factor of four CPU power over a Mac Classic.

My other accelerated Falcy, with a 50 MHz 68030 can whip up a storm of 18 MIPS, which translates to 12-13 times the original - Slow, but just about useable.

However, the CT60 in its bare minimum configuration can throw in 96.8 MIPS, which is more than adequate.

Some crazy people overclock this further, so a value of 147 MIPS at 100 MHz is not impossible (with a revision 6 '060!)

So it looks like we're good to go with the 060 :-)

MinvMac ported to Atari Falcon.

This might be of interest to you. The MinivMac emulator has been recently ported to the Atari ST family, specifically the Atari Falcon.


The interesting stuff starts halfway down the thread. It is an SDL port, so not massively optimised. I think it was compiled and found to run decently on a 68040 environment. The target hardware is really Atari Falcon with a 68060 accelerator card. The starting hardware probably something like a fast 68030. (It runs under another emulated environment, Hatari, but slowly with a lesser processor spec.)

The working proof screengrab is by me, from an emulated Atari clone, 'Aranym' (Mac version naturally!) Which would be on an 040 base. So an emulation nesting within another emulation.

The next interesting link is for a demo purported to run on Mac Classic.


There is a downloadable file, with a PC executable, and data files to transfer to a Mac Classic. It is not set up as a .dsk image at this point.

If you want to say hi, my email is [... email address ...]


Chris.H (CiH)

Interesting. This seems to related to the same port described in the previous feedback.

Posts in the forum you link express concern about speed. The C version of the 68000 emulation in Mini vMac is more concerned about simplicity and maintainability. The 2 existing assembly language versions (for x86-32 and PowerPC) tend to be about twice as fast. A 680x0 assembly version of emulating a 68000 could probably do even better, because it can directly use the 68000 instructions for math, after setting the status register and then saving it again.

Still, for Mini vMac to be practical, the host should generally be about 50 times faster than a Mac Plus. (Modern computers are thousands of times faster.) I don't know if a 68060 based Atari qualifies. It might be fun to play with anyway.

Hello Paul,

Just a word to said I have port mini vMac for Atari Mint 68K computer, it was very easy to compil. I use this options to extract source code:

-t slrs -api sdl -no-asm

and modified makefile I just need add the library gem with -lgem link option.

I will look if I can do better port with specific interface for mini Vmac under GEM but like it work fine.

Thanks a lot for this very good application

Olivier Landemarre

[... email address ...]

Thanks, that is interesting. I could add this as a target to the Mini vMac build system.

Instead of “-no-asm” would the new -cpu 68k option in the development version work?

If I wanted to try this, is there any emulator you recommend? And software to run on it? Perhaps Hatari running FreeMiNT?

Starting with the SDL port, you could make a more native port by combining the source code for Mini vMac and SDL, removing everything that isn't needed, and then cleaning up the result. I did this for the OS X Cocoa port. It takes a while, but is straightforward.

Hi Paul,

Some nice work here. Many years ago we used a program called McCad to create PCB files of boards that we built. We used a Macintosh II with the two disk drives. It was running system 6.0.7. We are now trying to resurrect those old files and modify them. McCad can't help us. What we have is an old SCSI drive which is bootable and has system 6.0.7 on it and the software. We are looking an emulator that might support this drive or through some method transfer the system and software to the emulator. I picked up on your comments about maybe working to create a Macintosh II emulator. Any suggestions would be appreciated. Best Regards, Dennis Wilson email [... email address ...]

Some other Macintosh emulators that I know of are listed on the Mini vMac Alternatives page.

How to transfer the files to a modern machine, depends a lot on what hardware you have available. People on one of the related forums may be able to help.

If you still have a working Macintosh II, or other old Macintosh, the Macintosh Floppy Emu could be useful.

Also, I have a list of Old Macintosh Disk Conversion Services. I made the list with floppy disks in mind, but some of those companies may also be able to handle a SCSI drive.

hmmm... It works on your setup eh? Anyway I use Windows laptop with Win 8.1, JIS keyboard, with Japanese Keyboard checked in on language selection (with English display, but that shouldn' matter). I tested both Mac systems KanjiTalk 6.0.7 and KT7.5.3, with the former patched with JIS resources (Roman-JIS and such) copied from the latter using ResEdit.

English inputs are perfectly matched with my kbd with my submitted ikb patch, and on US systems 6&7.5 as well.

Except KT7.5.3 seems to have a Kotoeri bug with JIS kbd; the key layout remains US layout no matter what I do in the Control panel or Kotoeri setting...i gave up.

KT6.0.7 works well with both roman and kanji inputs. (In both systems KANA input doesn' work; they both have different key/font assignments.) Anyway thanks for checking out my code. And BIG BIG thanks for minivmac!!

Since you’re using actual Windows hardware with an actual Japanese keyboard, your report should count for more than my use of VMWare. The problem is that if I use your patch, besides not working for me, it might not work for other people too. It would be much better to know how Mini vMac can distinguish between your set up and mine.

Thanks for the patch. Unfortunately the Japanese layout is one that I had already tested and found did not change the Virtual-Key Codes, compared to the US layout. So that suggests that looking at the result of GetKeyboardLayoutName is not sufficient to unscramble Virtual-Key Codes.

What version of Windows are you using? What kind of keyboard? I'm not sure what other details might help to distinguish from my set up.

Is there any way to have a magnification factor between 1x and 2x?


No, this is not supported. On some platforms it would not be that hard to modify the source code for other scale factors. Other platforms don't provide routines for scaled drawing, so you'd have to implement your own.

In any case, non integer scale factors would unavoidably look very bad. Particularly for the gray pattern commonly used on the early Macintosh.

[...] I still have my original Mac 128, and being in-the-money for a while at the time, bought an Australian produced RAM upgrade board for it. The board was the same size as the motherboard and sat above it, connected to the mother-board with a tower of stiff wiring, all sitting on strong pillars/posts. It was covered with 16k chips, and all told gave me an extra 2 MEGA-bytes of RAM. [...]

[...] I used the RAM as an SSD in effect, then known as a RAM-disk, and allocated 1MB to the System files plus iData, WriteNow, Excel 1, Word 1 and Draw 1.9.5. They plus a selection of fonts and control panels then worked in the remaining 1MB of RAM, plus the original 128kb still there. [...]

[...] The 128 still powers on, (the RAM board no longer, but finding the dead chip should be easy) but nothing I have tried (I don't know much) will induce it to boot up. If that *could be done, perhaps there may be info available on how ‘they’ did it, to allow software 'RAM' to be increased in your fab app? [...]

I have previously found that a Mac Plus cannot be upgraded beyond 4MB of RAM just by patching the ROM and moving it elsewhere in the address space. The Macintosh System software, in particular the part that installs bug fixes for traps that otherwise would be implemented ROM, assumes and depends on the exact address of the ROM.

But I hadn't considered whether the original Mac ROM could be upgraded beyond 512K RAM. Your report proves that it is possible. It might just be a matter of patching the part of the ROM that detects the amount of RAM. If that doesn't work, then it might be interesting to run CopyRoms on your machine.

By the way, I worked on early version of FDisasm with the development tools on a RAM disk, on a Mac 512K.

Hi Paul, I've got hundreds of floppy disk images I made years ago, as .img files. I try to pull them into vMac and it says that the floppies aren't formatted properly. Any idea how to get them working correctly? I can mount them just fine in SheepShaver

One way which would certainly work is to, in SheepShaver, copy the contents of your disk images to new blank disk images that are known to work in Mini vMac (see Blanks).

Otherwise, it would depend on what the problem is with your images. If they somehow ended up formatted as HFS+ rather than HFS, that will not work in Mini vMac, which only runs System 7.5.5 and earlier.

If it is the disk image format that is the problem, perhaps the Covert command, in the Images menu of Disk Utility of OS X might be useful, to convert to a 'read/write' image without encryption. This might not be much faster than copying the contents in SheepShaver. (It would be possible to automate this with hdiutil on the command line.)

What version of what software did you use to make the '.img' files? And what settings did you use?

How is the AIFF broken? As mentioned in the ImportFl page, it only imports the data fork of a file, and a work around is to use the “Compress” command of OS X to make an archive to import, which I guess is what you are doing.

If the only problem for your AIFF files is in losing the Macintosh file type, then you could use software such as Finder Info or Creator Changer to fix it, which might save a few steps.

I've made some patches to the FPU code you may or may not want to include. I can't take credit for any of the code -- it was all adapted from recent WinUAE source (a lot of work in the FPU code there is apparently being driven by the NeXT emaulator, previous). Changes include:

* Support for packed decimal real -- Claris Resolve now launches correctly in Mac II emulation.

* Fix for "unnormalized" numbers that was causing the emulator to hang in MacDraft 4.0 on an FDIV (number with nonzero exponent+ zero mantissa was being passed in to estimateDiv128To64).

* Changed myfp_REM to use iee754_remainder, and try to save quotient byte. My change fixes an issue where DYOH Architecture was generating nonsensical dimension measurements in Mac II emulation, though I'm not sure the code is 100% correct.

If you're interested let me know how to get the changes to you.

The problem still persists, but of interest, doesn't occur under the new Wayland display server (a replcement for X11 currently in development and expected to roll out in the next year or so).



It's nice that this bug may be getting fixed. (Whether it is in X11, or drivers, or limited to certain Linux distributions. It definitely doesn't show up in all Linux installations.) As I said before, a work around might be for Mini vMac to use a different drawing method, but that could potentially be much less efficient on some systems.

It turned out to be fairly simple to hack the Macintosh Plus ROM to support a larger emulated screen.

And if you require the ROM from a Macintosh II, then you might as well emulate a Macintosh II.

Just curious, would it be possible to make Mini vMac into a kernel for the Raspberry Pi? I am working on a Macintosh Pi, and I can run Mini vMac within Raspbian, but I think it would be faster to directly run the code rather than run it through Raspbian, kind of like what Scott Hutter did with his Commodore Pi project.

Anything's possible if someone spends enough time on it. Not me, certainly.

Rather than making a version of Mini vMac that runs directly on the hardware, a somewhat more feasible path would be to create a stripped down operating system for running a single program, which a standard Mini vMac could then be run on. Perhaps a version of Mini vMac compiled to run on SDL. The SDL API rather than XLib API may be more appropriate for this purpose. You could start with the source code for the Raspbian linux kernel, SDL, etc., and then start stripping out anything not needed. Since this stripped down OS would run a program that can also be run and compiled on the standard Raspbian, that would avoid an enormous amount of work in maintaining a compiler and other development tools.

This could be a fun project, but I doubt the result would run Mini vMac any faster. That is, even if you did find a way to make it run Mini vMac faster, that change could probably be made in the full Raspbian.

One way Mini vMac could be made to run faster on the Raspberry Pi is to make an ARM assembly language version of the 68000 emulation. (There are currently assembly language versions for PowerPC and x86-32.)

Update: Though it probably wouldn't help with speed, an operating system optimized to run a single program may help in other ways. Not sharing time with other processes may allow smoother emulation. There might also be opportunity to reduce latency, that is, time between keypress or mouse click, and the result showing up on the screen.

An operating system to run a single program could be useful for other emulators and games, and so attract more people to help than making a version of Mini vMac. (But not me, though it is an interesting idea.)

Hi - I'm just messaging you to confirm that minivmac can be compiled for FreeBSD/powerpc - at present you only support linux-ppc and freebsd-x86 and freebsd-amd64 ...

using the endianness stuff from the lppc CNFGGLOB and updating directories from /usr/X11R6/(include,lib) to /usr/local/(include,lib) were sufficient to get minivmac to compile with not-too-much trauma.

I must ask, though - isn't it a little odd to need to use minivmac or a mac to bootstrap the minivmac build? Couldn't it be made to function with a more traditional configure script based solution?

Thanks, I'll add FreeBSD/powerpc to the build system.

About the build system - See the topic in the FAQ - “What format is the Mini vMac source code in, and why don't you use something more standard?”. Sure, I could make the source into a format easier to use in FreeBSD, but then it would be harder to use on some other platforms supported by Mini vMac. Platforms come and go, the only platform guaranteed to exist for as long as Mini vMac does is Macintosh 680x0.

Another thought is that if Mini vMac used a standard unix configure script, and for whatever reason it didn't quite run on your machine, it would be nearly impossible to debug the configure script, that thing is massive and messy. But when the Mini vMac build system generates something that doesn't quite work on your machine, it is relatively easy to fix, as you did.

Thanks for sharing your project code. I'm learning vintage Macintosh programming. Thus, I'm reading your CopyROM program. I want to know why some files with post fix *.i. It looks like C code. But there are some Macro such as LOCALPROC and etc.

Are there any reason do it in this way? I tried to compile them MPW 3.1. But it exclude them from Make.



For most of the Mini vMac extras (but not Mini vMac itself), I'm not following the normal C convention of a program consisting of a bunch of separately compiled files held together by a Make file. Instead, there is a single file to compile, "app.c", that includes ".i" files holding code. This makes it easy to compile with a variety of Macintosh development environments, which may not even use Make files. For simple programs, with Mini vMac set to All Out speed, speed of compiling is not an problem (the main original motiviation for separate compilation).

See the Compiling Macintosh 680x0 Applications for (incomplete) documentation on how to compile the Mini vMac extras.

“LOCALPROC” is defined in “COREDEFS.i”. It is just a convention I adopted long ago when first moving from Pascal to C.

Sorry, I didn't read through your whole page. No wonder I don't need to enter my email address to receive your reply.

In any case, I have trouble to run mini vMac ARM version in my odroid U2 board which uses hard float X11 library for performance purpose.

I figured out how to compile mini vMac on my board. It loads correct version now. Please let me know if you want a binary copy of compiled binary.

Ricky@odroid:~/Downloads/minivmac-3.3.3-lx64$ ldd minivmac

I'm glad you got it to compile. I would be interested to know if any changes were needed to the source code or make file which were generated by the Mini vMac build system.

does macweb work? i saw someone on youtube use a old mackintosh system (i don't know if its a SE) and they used mac web i don't know if you already have it or didn't add it yet.

Since it is not available from the copyright holder, MacWeb doesn't qualify to be linked to from my software list. It could qualify to be hosted there. I found a page about browsers for black & white Macs, and it sounds like it ought to work in Mini vMac's Mac Plus emulation, except of course that Mini vMac doesn't emulate internet access. A web browser could still be used to view local files.

Hello, Your vMac is really greate ! But, I try to compile a vMac with 1Mio RAM with Xcode 5.5.1 (I can't found now the antica version of 2.2.1), but I've an error when I compile : "Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1"

I haven't much cared for recent versions of XCode, and haven't paid attention to it lately, but yes, Mini vMac should support them. I'll look into it (but this may take a while).

i got gryphel GUI on my computer,

is it a PC emulator?

can i get games/Apps for it?

let me know

I guess you are referring to the Gryphel Graphical User Interface Implementation Illustration, which predates using the Gryphel name and website entirely for Mini vMac related stuff. It is unrelated, has nothing to do with emulation, and has been moved to different domain (“.net” instead of “.com”). Below the latest news on that page is a brief description of what it is about.

I have an idea,

an app that compile a mini vMac, within the mini vMac,

and have the ready to use app, show up on the desktop of the host computer.

the app is operated with survey style interface,

rather than command line.

will you make it?

i photoshop that idea and fed it to the site below


it make it so much easier to compile the mini vMac

Hi again. We've discussed something similar before. Sorry, it is not feasible. (Cross compilers are not trivial, and then there are other needed tools and API files.)

Hi Paul,

Adam Rosen from the Vintage Mac Museum here. I was just checking out your site, and appreciate the fact that you've listed my file conversion services on your list of vendors. If there's anything I can do to help with Gryphel or Mini vMac, please don't hesitate to ask!

You're welcome, and thank you for the offer.

Thanks for sharing this wonderful project. I donated $10 to support your on-going effort.

Is it possible to compile in ARMHF version? I have trouble to figure it out how to cross compile in ARM.



Thank you for your donation!

I guess you missed the previous reply?
