I hope you get it going, but I might make some comments.
HP-41 programs are normally short enough that in the unlikely event that you really lost one from memory, it would not be a major time-consumer to key it back in. I have the tape drive and plenty of tapes, but have not used it for either my 41 or my 71 in many, many years, and I have programs that have been in them continuously for nearly 20 years. Since the 41 does not allow embedded comments or more than one instruction per line, I write new programs in a text editor on the PC, then key them into the 41. That way there are also fewer bugs to fix, since I can see what I'm doing better and make the programs semi-structured. I can embed all the comments and diagrams and charts I want, and of course only the instructions go into the 41.
I never bought the card reader, but I expect the cards should last just about indefinitely. I have a 50-year-old open-reel tape of Frank Sinatra that still sounds really outstanding.
I have the FSI164A (almost the same as the 82164A, but with more RS-232 channels and more buffer memory) but have only used it for interfacing to workbench equipment, not the PC.
