HP-41 Book "Programming the HP 41C/CV/CX" by Thomas Adams

[HP67]

Any interesting side note:

My buddy alerted me to a sale at Michigan State University. Among the surplus items were a bunch of 48G calculators. We bought 4 and he sent me 2 in the post.

One of them was a pristine, apparently unused model but alas without the double shot keys. The other one was a dirty, banged up wreck of a calculator with a tweaked bezel. It was obviously opened, probably more than once. I cleaned it up over a few hours and worked out the major bumps in the bezel but it still creaks like a past century wooden rocking chair.

The interesting thing was (now) that it had a sticker on the back, Property of Thomas Adams and I think it also said Physical Therapy Department but I can't remember. The sticker and residue were removed as part of my cleanup operation.

I knew at the time he was the author of at least one HP Book. But I didn't think leaving the calculator as I got it would mean I had a collector's item

I believe I may have PDFs of one or more of his books but I have not been home in almost a year, stuck far away due to Corona. When I get back I will look and update the thread.
