Thanks Pauli!

Success! After some more work this weekend to adapt the display scan and keyboard scan routines and the slide switch, I just got the HP-25E firmware with all its features running on this calculator.

The Total Repair is complete!

I worked already significantly on a concept, which should make this Woodstock Low Power version available for everybody, it included a fast ARM processor with 128k ROM and a USB interface, but I cancelled the idea due to high manufacturing costs for the necessary multilayer board.
