RE: HP48 card PCBs
I have a 128kb and 512kb card of the stacked board construction shown (actual layout slightly different). It too has the glue logic chips tops sanded/scratched off but I would expect it wouldn’t be too difficult to reverse engineer them.
What info are you looking for? Schematic? Other? |
