I sent a private message off to Jim explaining what I have (nothing other than documentation) and what I would like to do (emulate any one of the Microdata-based machines, but preferably the MAI Basic Four 1200 unit that I used to own many years ago).
In order to do any of this, there’s at least two pieces we would need - a dump of the ROM from one of the machines, and a copy of some boot media for the same machine. There doesn’t appear to be any copies of media publicly available.
If anything was to show up, I’d love to exchange notes and ideas with you. I also dabble in FPGA, so the idea of an FPGA implementation is intriguing to me.
