I’ll have to start reading the manual to navigate it and brush up on my BASIC but I am sure I’ll find a use for it. It took me a while to find a PS2 keyboard in my shed. The internal 7805 regulator was running a bit hot so I may replace it with a DC/DC step down regulator. After reading the instructions for the unit it is recommended to only have a 9v supply not 12v so that could be part of the heat problem…..
The 3.3v reg had to be wired in as it was not pin comparable with previous linear regulator
