Introducing LokiOS. A new version of CP/M, written from Scratch, Compatible with CP/M2.2 Programs

Via Hacker News

Hi All,

Thought I’d stick this in it’s own thread as I progress, since it’s come up in many past threads… So I’ve been writing ( written? ) a new CP/M for Z80 based on CPM/2.2 in much the same way as DOS was created - I began with the system calls and recreated it, then worked to build compatability. It’s pretty much like CP/M2.2, but does change a little bit, and there’s still bugs.
