I originally posted the following questions in in comp.sys.hp, but considering that the real calculator enthusiasts are here I thought it might work better to ask in this group as well. How could I help but fall in love with a calculator that's almost as old as I am and built entirely with discrete components and what appears to be core memory? However, the only documentation I have is the "cheat sheet" that slides out of a slot in the bottom; it would probably be enough to let me figure everything else out (just a little hacking told me the memory format and how floating-point numbers are stored) but I'd really like to find an owner's manual for this thing. There appears to be a magnetic card reader, but I've been unsuccessful so far in finding them through the original owner of the calculator. I'd like to have at least one or two magnetic cards to play with. I'd also like to fix the light that illuminates the "z temporary/y accumulator/x keyboard" display to the right of the CRT display, and possibly obtain a new plastic protector that separates the cheat sheet from the bottom of the card cage (obviously a good idea to have, since if you spill coffee on the cheat sheet and slide it back in you'll short out things on the bottom of the card cage). The original plastic protector had some sort of foam or fuzz coating that over the years disintegrated and ended up largely as rolls of gummy black stuff inside the case. -- Steve VanDevender stevev@greylady.uoregon.edu "Bipedalism--an unrecognized disease affecting over 99% of the population.
