HP-41CX Halfnut problem cardreader with Nov64d

[Hiwi]

Hi Diego,
thanks for reply, this is not a big thing, since i am using the cardreader not very often.
In this case i had an old program on mag cards only for calculating LM317 voltage regulators.
I pulled the Nov64d out and could read the cards. Now i put the program on Hepax memory and don't need the cardreader nay more. I only thought the cardreader or the HP-41 may be defective.
