The P112 is a single-board computer project that was originally made in
the 1990s. It implements a Z180-based microcomputer intended to run
CP/M and similar operating systems. Over the past several years I've
made and sold kits. I'm not doing that anymore because it has become
too hard to get new super-IO chips in large enough quantities. This
page remains here for reference.
