HP-41 card reader "memory lost" Message #1 Posted by Michel Beaulieu on 25 Mar 2003, 7:28 p.m. No don't be discourage, i don't need to repair my 41 card reader ;-). Just a question. Is is normal that if i put a brand new card in my reader and try to read this blank card that i get MEMORY LOST everytime i mistake a card for a empty one? Merci

DO NOT use anythind else than alcohol). take another swab to dry them. also, clean the contacts of the batteries themselves. cheers, hans
