Hi!
I have Commodore keys, more than one and if you need also any other, write...
Most of keys are from German C128D... also compatible +4 keys.
If you have at least board of C128D keyboard with 100% working contact switchers I can swap with lot of keys...
I have my C128D keyboard with broken switcher contact of 0 key, and damaged by testing of repair.
