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 Cheers, Thomas [35/45/55/65/67/97/80 21/25/29C 31E/32E/33E|C/34C/38E 41C|CV|CX 71B 10C/11C/12C/15C|CE/16C 32S|SII/42S 28C|S 48GX/49G/50G 35S 41X] |
