HP-41CV Fullnut CPU-board wanted

[Martin Hepperle]

Hello,

recently I obtained an HP-41CV which when powered up shows only MEMOY-LOST and no keyboard interaction is possible. I was not able to bring it back to life. The keyboard and display seem to work properly and the connectors between the boards seem to be okay. Once or twice I was able to coax it into a CAT 1 display by removing/replacing the battery box.
Assuming that the CPU/RAM/ROM board has a fault I am looking for a replacement board. This machine needs a fullnut board (board with the two electrolytic capacitors in the edge cutout and the double-height stacked RAM chips) attached without nuts to the keyboard PCB.

Maybe someone has a CV with a damaged case, keyboard, display but a possible working mainboard sitting around?
Preferable in Europe to minimize shipping costs.

Alternatively I could transfrom this machine into a CL but I am still struggling with the (well justified) costs.
