RC2014 ( is a great platform for building your own Z80-based system running BASIC, CP/M or UNIX (

After putting together an RC2014 CP/M rig Chris went digging around in his 80's IC stash and found a bunch of TMS99xx CPUs and support chips. This is the story of the IT archaeology, prototyping and hacking that followed to create a system that runs BASIC and Forth on an alien architecture using standard RC2014 modules and backplane.

Many thanks to G-Research ( for sponsoring this event by providing both the venue and beer & pizza for attendees!
