I got hold of a old unused Cherry G80-1800 keyboard from which I took the caps to the Bok.CP, and after that it was just laying around since it had DIN connector instead of USB.
Then I was able to buy a slot-in replacement PCB from Maartenwut which had USB connectors and was QMK enabled.
So after some desoldering, lubing, dampening and soldering it was again ready for action.
The GMK TA 90 keyset suits the build quite well, and then a blue USB-cable to top it off.
The vintage blacks were replaced with 55gr TX-spring swapped Gateron blacks with milky tops due to vints being to heavy for the wife who is currently using the keyboard.
