C128 keyboard support? #1

Closed banman11 closed 3 months ago

banman11 commented 6 months ago

Hello,

First up, I'd like to say this looks like a very interesting project.

I was wondering how hard would it be to add a few extra keystrokes to support the very few extra keys on a C128 keyboard?

Hello, as long as the hardware allows it it should be no problem. However I need to look into the keyboard connector of the c128 to say for sure :)

The keyboard is basically the same thing as a C64 with a few extra lines. One is hardwired I believe. That is the 40/80 switch. The actual interface is a sort of square 25 way D female connector. The Commodore engineer's tried to make it as easy as possible to use off the shelf parts.

Here is an example of a third party adaptor which would very easily plug straight into your project.

Just a side note with a small wiring rearrangement of the keyboard lines a c16/plus4 keyboard should work just fine as well with your project..
