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.

Some more software is now hosted by the Gryphel Project instead of only linked to: LEE and Glider Design!. And some software is now hosted by the Gryphel Project where the original web pages have disappeared: CRLF.

Three weeks of using Mini vMac 3.5.6, with the new enhanced Abnormal Situation reports, have yielded two reports. These two reports suggest the problem is not a new call to report an Abnormal Situation for what is actually a normal situation, but instead that something is randomly accessing memory. So I think the next step is to write (optional) debugging code to catch unusual accesses to memory, to greatly increase the percent of the address space that generates an abnormal situation report, hopefully making the reports much more frequent.


Thanks to William Winter for sponsoring over 2 weeks of web hosting for the Gryphel project.
