Two weeks ago I jumped into the TI-99/4A world by grabbing a beige system locally for $10. Five keys stuck when pressed and it had the dreaded 2.2v GROM. I found a cheap silver and black TI-99 untested on eBay and grabbed that. Keyboard doesn't work (only the 1, 5, and space keys work). I was able to swap the GROM out and get the beige system running, and even fixed the keys to a point they are usable, but the entire keyboard is a bit sporadic.
Does anyone have a spare keyboard that works that they would like to sell? I'm okay with either beige or black at this point. I just need one that works reliably.
Thanks!
