HP-41 card reader Commands



#9

Hi,
Can anyone tell me a quick list of any commands for the HP-41 card reader. I don't have the manual, and I hear there were some commands ('Verify' or something similar included).

Many thanks !

David

A lot of people will send you the commands, for sure. If you can wait till Friday, I'm sending you a scancopy of the card reader's quick reference (I'm not home, now)
