This tiny adapter allows to plug your C64 keyboard on a C128D computer. There is an additional jumper to choose between 40/80 columns.
This is a work in progress, several testing must be made but it should work as is. I take no responsibiltiy for any damage to any equipment that results from the use of this board. USE AT YOUR OWN RISK!
Do NOT use long cables with this adapter, MAX 1M long.
Pin nº 2 must be cutted out on the 1x20 pin row (there is a mark on the pcb that says NC).
This design is based on the schematic shared on this page. https://ist.uwaterloo.ca/~schepers/MJK/c128_keyboard.html
Originally tested by @Cutristieso using a protoboard.
If you like the project or want to support it, you can buy me a beer or a KO-FI :)
