It's 2AM here, but I have bi-directional data on PC side, and a rudimentary VIC/64 keyboard scanning routine in place. Works pretty well. Need to add neat things like repeat, all the special keys, and reprogrammability. Oh, and joysticks would be OK as well... Any interest? I'm not familiar with the 8296D keyboard, but it should be easy to modify the matrix scan routine to do any row/col keyboard. Solution is single IC (ATMEGA32, but ATMEGA16 would work fine), with 2 caps and 1 crystal (well, and PS2 cable...)
