HP used to have a seperate test unit (a test module which possibly had some additional hardware included). There was no software on magnetic cards.
I know a guy, who owns such a unit and he tested one of my 41s and my card reader. I remember, that he even could measure the speed of the card.
There's the HP41 service manual on one of Dave Hicks CDs. Read this document, if you're interested how to use this module.
