48GX repurpose EQ library card as memory bank1 - grbrum - 07-21-2023 10:33 AM
Hello. Is it possible to “format” the card to be repurposed as bank 1 memory?
If it is possible. I hope it is also reversible as well.
Does anyone know the size of the card?
Thanks

If you are referring to the HP 82211A HP Solve Equation Library Application Card for the HP-48SX then the answer is no. This is a 128 kByte ROM card and cannot be erased or reprogrammed.

Too bad. I can’t seem to find a 128k card.

Retrotronic in Portugal is selling 128k cards (currently in stock). I have one of those and a 1MB card (currently out of stock). They work well. Earlier units didn't fit properly, but that issue has been addressed.

Thank you. I bought one to test. If all works well I will buy for each of my 48. Thanks
