I can vouch that putting a standard Epson card into a 48SX is a crap-shoot.
Moreover, it is calculator-dependent, in that it will work with some 48s
but not with others.  And for those 48s that _do_ work with the standard
Epson cards, if their batteries get low, they join the ranks of the 48s
which _don't_ accept the Epson cards.  So what, you ask?  Well, the typical
behavior of a 48 which doesn't like Epson cards is to click and whirr and
put blue goo all over the screen, then to ignore all key presses (including
ON-C and ON-A-F) until the card is removed and (sometimes necessary) the
foot peeled off and the zappo button pushed with a paper clip.  Needless to
say, most data cannot survive such a process...  :-(  In fact, the behavior
reminds me of the time I dropped my 48 into a sink full of water...  :-O

So, in summary, Epson cards sometimes work, but their voltage requirements
(as explained in an earlier post) have an unpredictable behavior.
