Now, my shameless appeal to find some old equipment for myself. ;-)
....I am looking for old Hewlett Packard calculators in working condition. I'm not interested in the HP-28, HP-48, HP-12C's.

I'm also looking for HP-41C calculators and Peripherals I'm looking for old HP-41C's with serial numbers of 1938AXXXX or smaller. The serial number can be found on the back side of the calculator. Peripherals I'm searching for include HP-IL printers, disk drives, and RAM disks.

Got something you might sell or trade? Drop me an email and tell me (1) what you have, (2) what kind of condition it's in, and (3) what you would want for it.
New! Lots of Calculator Links
