So, I was somehow the only bidder for a TI-59 with printer, multiple modules, lots of books, etc. ($5)
I haven't repaired a TI-59 card reader for awhile, so I did an internet search for advice.
I found an old posting on the HP Museum site describing how to do it. It wasn't until I read the posting that I realized that I had written it...almost 7 years ago.
You know you're getting older when you end up finding your own advice on the internet!
