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.

I’ve changed my mind, and will trying using Apple’s code signing for the Macintosh OS X port, for 64 bits. This is implemented in the Mini vMac 36 Alpha Variations Service as of today. This allows Mini vMac to run on OS X without having to bypass Apple’s GateKeeper feature.

Hopefully, what I’ve implemented will work without causing too many problems. Normally signing an application involves requesting a signed time stamp from an Apple server. This is impractical for the Variations Service. And another problem is the result of this depends on the current time, which breaks the build process of compiling twice and checking for an exact match.

But it turns out to be possible to instruct the code signing tool to not do the time stamp. One possible consequence is that the application may stop working when the signing certificate expires in 5 years, since the application doesn’t have a signed time stamp to prove it was compiled before that. If I get a new signing certificate from Apple every year, this may not be too much of a problem.
