Re: Keyboard A4000 - Help
A4000 keyboard port and CD32 serial port are the same. You can plug an A4000 keyboard in and it will work on the CD32 without any modifications.
I can't remember if the A4000 keyboard is the same, but A500 and A1200 keyboards all have a chip built into the keyboard that controls the key presses. This could be the issue, as could the keyboard membrane. But the other main keyboard issue is the 2 CIA chips on the motherboard.

Misread your original post. Thought you had said CD32, rather than CDTV. The CDTV has the same keyboard connector as the A2000.
