Below is my HP41CX. With belt loop holster. A rare day that it's not on my belt. I walk phunnie without it. Lol.
Not photo'd are the accessories. Card reader, tape drive, strip printer, wide carriage printer, 232 interface, discrete AND analog io... I've set these up to analog measure and control heat treating temperature schedule. Etc, etc.
Saved up and traded my HP65 for early HP41C. 1979. Carried it till wrecked with security Xray while entering a nuke plant. 1991. They gave me this CX as replacement. Lol. They really wanted my calcs on a "thang". Lol. I was a "calculator" as highschool job well before calculator as device became popular. Lol. CX includes built in time module and etc. These things are NOT Xray tolerant. Odd considering HP's radar history, imo. Go figure. Lol
Note the rom cards. Gotta pretty complete collection. Quite a few custom. "Synthetic Programming" proved supremely advanced capabilities. Got one interfaced thru HAM. Original "wireless text"? Lol.
Still hunting "=" key... anyone see one? Lol
