I believe that the SMITH-CORONA cards are made by EPSON. The regular EPSON RAM cards are made to work at 5 to 6 volts, depending on their type (mixed CMOS, full CMOS). I believe that HP puchases their RAM cards from EPSON, but that they specify a quality level in which the RAM cards would work reliably in a lower 3.5(???) to 4.5 volt range (dictated by the AAA batteries). If one can get a Smith-Corona ram card that works well in a 48, they're luckier than me because my S-C card sure doesn't. My card worked well as merged memory at first but it doesn't now, which dictates my experimentation. I suggest archiving your 48 files before trying out the Smith-Corona cards as a safety precaution.

I have an ESPSON 32K mem card for my EPSON calculator, do you suppose it would work on the HP? Kelvin
