HP48 compatible SRAM memory cards



#6

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

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!

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.

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?

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.
