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.
