I found some TMS CPUs and IO chips in a stash that I'd salvaged from some scrap PLCs in the late 80s and thought I'd try to build a system from them. Having recently put together an RC2014 CP/M setup I hoped to reuse some modules from that; and I found a design and firmware from Stuart Conner. So this project became about putting a version of Stuart's breadboard system onto an RC2014 prototype module in a way that made best reuse of existing RAM and ROM modules. The finished system is capable of running Cortex BASIC and Forth (jumper switchable) and is accessible via a Raspberry Pi serial terminal server.
