The goal of the Gryphel Project is to help preserve software made for early Macintosh computers, the computers that Apple sold from 1984 to 1996 based upon Motorola’s 680x0 microprocessors.
The center of this project - a family of free and open source emulators that allow such software to be used on modern computers
The rest of this project - software for the early Macintosh, links to alternatives to Mini vMac, links to related forums, lists of books, and more.

I’ve upgraded the hardware for the Variations Service. It is more than twice as fast, around two seconds to compile a variation. But the main motivation is that having more memory allows having multiple virtual machines (with VMware Fusion). This allows moving away from using a single set of cross compilers, using other compilers with whatever operating system they require in a virtual machine. Which will allow for supporting more platforms, especially new platforms.
Using a newer Macintosh required using a newer version of macOS. Which was the main factor in this taking a while. I’ll skip rants. Actually, in the end, so far it seems this macOS version can run the Variations Service fine. After disabling most of the OS.

The latest Development source snapshot fixes a bug where, if the ROM image file that Mini vMac finds is not the desired ROM, but a different valid Macintosh ROM that has been renamed, and the undesired ROM is larger than the desired ROM, Mini vMac would display a “ROM checksum failed” message instead of the “Unsupported ROM” message. This is because Mini vMac loads and computes the checksum of the expected number of bytes, rather than the actual ROM image size. (It is intended behavior that Mini vMac will work if the ROM image file has some extra junk at the end.) Mini vMac now checks that the checksum field at the start of the ROM is recognized, before verifying the actual checksum. Thanks to a bug report for pointing out this issue.
