Magnetic Card failures

[CY-CL]

Hi Thott

You are still using magnetic cards. Respect!

If you buy a PIL Box, you can store any HP-41 program on your PC or MAC.

Even when I write them new.

With my cards I get also sometimes a failure message, but quite seldom.

From a Facebook user I got the advice to wipe the magnetic side with alcohol.

I did it with Methanol.......and it works!

Out of 20 obviously defect cards are now after cleaning 19 card recordable and 100% readable.

Failure messages of the card reader is not always caused by the reader itself but maybe caused by the magnetic card.....
