Re: 71B Memory Module Message #2 Posted by Garth Wilson on 5 Feb 2006, 4:57 a.m., in response to message #1 by Xavier LaRue
I don't know of any recent HP71 memory module offerings, but back in the mid- to late-1980's, CMT offered them in 32KB and 64KB for the front ports, and 32KB, 64KB, 96KB, 128KB, and 160KB for the card-reader port. There was also a company that would hard-wire 256KB internally for you for a hefty fee, so it would not take up any of your ports.
The HPIL module added a pair of connectors next to the power connector. You don't even have to turn the computer on to tell if it has an HPIL module. If you have the pair of connectors there, you have HPIL. If they're not there, you don't. Very simple.
Your last question is not clear. Are you asking whether the MoHPC CD ROMs are still available? They are at http://www.hpmuseum.org/cd/cddesc.htm
