The Alice Project is a collection of smaller projects that are supposed to teach us about hardware and system software.
Our original goal was to design, manufacture, and sell a UNIX graphics workstation based on the Motorola 88110 microprocessor, which would have been state-of-the-art for 1992. To familiarize ourselves with porting UNIX, we ported BSD Net/2 to the Macintosh II. This was freely released as MacBSD (and later as NetBSD/Mac).
We then went back to hardware, first creating the Alice I, a simple Z-80-based system with 7-segment display output, then the Alice II, a more sophisticated computer also based on the Z-80 microprocessor.
The Alice III was going to be a multi-CPU version of the Alice II with more contemporary processors, but we're tired of hardware and want to create something that doesn't break by itself from week to week.
This website documents the Alice I and Alice II projects.
