HP48 compatible SRAM memory cards Message #1 Posted by Andrés C. Rodríguez (Argentina) on 20 Feb 2009, 3:38 p.m. It would be very helpful for me if someone could suggest where to buy one of these cards (used may be OK as long as it works). I know I can try an auction site; but perhaps some member of this Forum has a better or different idea. Thank you in advance, Andrés PS: if you prefer not to answer via this Forum, please contact me at the following email address: "a.rodriguez" (at) "ieee.org"

Re: HP48 compatible SRAM memory cards Message #2 Posted by Martin Pinckney on 20 Feb 2009, 5:17 p.m., in response to message #1 by Andrés C. Rodríguez (Argentina) Andrés, If you are wanting a card for the 48SX, apparently HP used the 82215A (128KB) card for some products other than the calculators. There are some vendors out there that still stock these. I myself purchased one for $99 some time ago. Here are some websites that display a reference to this item, but it is hard to tell if they actually have them for sale! http://www.ptltest.com/spectrum_analyzers.htm http://www.xsequip.com/Product%20Photos.html http://www.geocities.com/survcalc/access.html On the other hand, if you are looking for the higher capacity cards for the 48GX, these were made by a number of 3rd party companies. I have not searched for these, since I cannot use them. Hope this helps.

Rodríguez (Argentina) Aren't they just PCMCIA cards (PC cards)? How about the ones on the lower-right corner of Digi-Key's catalog page at http://dkc3.digikey.com/PDF/T091/P1165.pdf which go out to eight megabytes?

Re: HP48 compatible SRAM memory cards Message #4 Posted by Eric Rechlin on 20 Feb 2009, 5:38 p.m., in response to message #3 by Garth Wilson No. In fact, they might even pre-date PCMCIA cards. HP 48 cards have contacts on the side that look a little like the contacts on an SD card, but they are covered by a protective metal shutter on HP-approved cards; PCMCIA cards have contacts on the end inside tiny holes.
