Message #1 Posted by mark french on 26 Mar 1999, 3:44 a.m.
making a repair to goo-ey pinch wheel of a hp41 reader, but don't have any hp cards, anybody know thickness of them so i can make a test strip (like, how thick are 50 of em stacked together, whatever)...or can anybody send me a spare one with a program on it that I can try, I can return it + $1.00 for your trouble...thanks!

They are exactly .0085 in. thick each. Oddly enough I happen to have a few blank mag cards and a pair of micrometers right by my computer.
