In this episode Adrian fixes a Commodore 128D Keyboard that was sent to him by one of his viewers.
Per Adrian “The fix involved lots of swapping of parts, some glue and epoxy with the result being a nice keyboard for the 128D! The 128D keyboard is the same internally as any other Commodore 128 keyboard other than the cable, which you can easily move over by just moving the PCB. (Or you could desolder the cable)”
