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.

The latest Mini vMac Development source snapshot tries out backtracking a bit in the build system. Instead of a 68k Macintosh program to generate files to compile, it uses a cross platform standard C command line tool to generate a script to write configuration files, as was done prior to Mini vMac 3 over a decade ago.

This should allow the Variations Service to be more efficient, and is also more convenient for experienced programmers. The trade off is in making it harder for others to compile their own variations. Now I would prefer for people to use the Variations Service, and this is not only because of the funding model. Helping beginners figure out how to compile does not scale. And trying to making Mini vMac work well with random versions of random compilers also does not scale. With the Variations Service I can ensure quality of the compiled variations. The Variations Service has greatly improved in past months, fully automatic with 30 second turnaround (and still getting faster).

The source snapshot is now a standard compressed archive, in “.tgz” format. The source for the configuration tool is in “setup”folder. In a unix like system it can be compiled using something like “gcc setup/tool.c -o setup_t”, then run with something like “./setup_t -t mc64 > setup.sh”, and the output run with “. ./setup.sh”, and then Mini vMac can be compile with “make”.

The new configuration tool is still a work in progress. It should be better documented when it is more settled.
