HP Classic upgrade kit - Multi Emulator (updated list of emulated models)

[Harald]

One could always measure all the connections on a known good bare PCB and then design a new PCB that replicates the original one. It's perfectly doable but requires a lot of time.

I have thought about adapting the classic replacement PCB for the 65, but I am not sure it makes sense. I'd always be unhappy with the card reader not working.
