RE: HP41C with Rp Pico attached
Hi Andrew!

Very interesting project indeed!

I assume this is connected between the CPU-board and the main PCB/Keyboard.
Would it be possible to connect the "analyzer" between the PCB/Keyboard and the I/O-module?
I guess that the information from (and emulating) the keyboard will be lost, maybe also vital part of the display I/O?
The reason I'm asking is that it might be possible to use a flex-strip (see this link), without soldering something inside the HP41.
Or even using only an old module connector just to analyze the inter-module communication.

Emulating modules is one achievement, but with USB connection a lot of other interesting possibilities might also be possible ...
I.e. maybe emulating the card reader or Wand to insert/save programs into the 41 from a PC Wink

Cheers,
Thomas
