Perhaps you folks can help. There used to be some small scientific (credit-card size to 25"x 4") scientific calculators sold. I have an old Radio Shack EC 4008, which is one of the larger of these. I love the things, but keep wearing them out and can't find replacements. Can anyone tell me other makes & models? Are these kinds of things still made by someone? Does anyone have one their willing to sell to someone who'll treasure it, but will use it? Thanks for your help.
