Hello,

This is a tested and working PCB. (This PCB has been tested on a C128D-CR and C64 keyboard.)

This is an Easy DIY project, all components are through hole, marked on the PCB, Easy to solder, Easy to make ;)

With this adapter, you can connect your Commodore 64 keyboard to your Commodore 128D or C128DCR.

Because of C64 keyboard does not have a 40/80 Column key, this key was added to the adapter. There is also an optional switch for the Caps-Lock key on the PCB.

You can also use this adapter with "COMMODORE 64 TACTILE BUTTON MINI KEYBOARD".

As you can see I have uploaded many projects and I am still working on new projects. If you have any questions, please look for answers online. Unless I specify explicitly, all my projects are tested and confirmed to work under normal circumstances before being shared. I'm sorry I didn't have enough time to answer all the questions.

Use this PCB at your own risk !

Have fun

Thank you.
