Hehehe - cool!! I did the exact same thing a while back - it turned out to be rather annoying to get working in the end as i recall - and then after all that and resoldering the k/b ribbon i had a couple RAM chips go bad, so the console the cord conversion was intended for has sat ever since then. I really should get another F18A to put in that unit, but then the cord conversion would be useless.... oh well
Anyway, I've been getting into some Amiga emulation the past 2-3 weeks (I had little bit of experience with them when I was about 12-14), which has been a lot of fun. It's been since just before then that I was running the TI - so late December probably. I had been slowly working through Legends (ver. 1.1) and as it is slog, it is nice to take a break. It's also nice to learn about new platforms, and Amigas seem to fit the bill nicely for me since the OS is this strange mix of TrapOS Unix and Xerox Alto and the systems were rather ahead of their time, as well, like the TI was in its day.
😡 That's bulls***. Sorry to hear about that.
