the Gryphel Project


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.

Mini vMac

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.

Today’s Mini vMac Development source snapshot adds a number of features to the build system. The motivation is that the Variations Service page gets unwieldy as more and more options are added. So I’m thinking of instead having a Basic Variations Service, which only has the most popular options, and a new Advanced Variations Service, which allows pasting in options as text. (With the new ‘P’ command of the Mini vMac Control Mode to get the options of an existing variation, you would be able to easily update a variation.)

If the new option “@” is used, no developer options are permitted to the right of it. This will allow the Variations Service to allow the user to specify options as text without the chance of breaking the service. (For example, the ‘-e’ option to select the the development environment would not work well.)

The new option “-ef 1” causes the the build system to write error messages to a text file, instead of displaying an alert dialog. This will allow the Variations Service to allow the user to specify options as text, and get any error messages, such as about bad syntax, back to the web page shown to the user, rather than breaking the service.

If the new option “!” is used, options to the right of it will override options to the left of it. Normally it would be an error for the same option to be used twice. It is still an error for an option to be used twice on the same side of ‘!’.

The new option “-cte 1” causes the the build system to generate source code that causes the compiler to generate an error. This is for testing the variation service.

If the new option “-bte” is used, the build system will treat it as an error. This is for testing the variation service.
