Is there a consolidated set of repair information?

Aloha all,

I haven't been active with the museum or my calculator collection for about 15 years and see a lot of things have changed (Like having to create a new account ;-). All very exciting! I do have to admit that I'm a bit bummed that if I had dug some calcs out a few months ago I could have gotten a 41-CL board, and I wish I had known to buy a 35S when they were in production and cheaper, but I'm always late to the party. I started collecting in 96/97, and I was late to the party then. I will acknowledge I was lucky enough to get some of the remains from Educalc before it was all gone.

On the topic of repairs, I started pulling calculators out of storage boxes looking for one I could use for the amateur radio exams, and I discovered that the vast majority didn't work. I have quite a lot of calculators. I did discover that the 42S is actually fairly nice.

So I've got a 45 and 65 (and likely a 35 when I find it) that will need some love, only one of my woodstocks works, none of the spices I tried work, all but one of my unboxed 41's don't power up. I expect most or all card readers will need a rebuild. I haven't tried any of my voyagers except my original 11c from college which thankfully powered up. Basically it appears anything I've used in the last 5 years works, and the rest don't. None of my TI's I tried except for an original TI-30 seem to be working. The clamshells I have tried are working.

What this means is that when I get time I'm going to be trying to resuscitate (I'm guessing here) on the order of 20 HP calculators from various product lines. I have the HP-41 repair manual from the calculator store, I know about the repair section here in the museum, and I know about the old forums, and a few things I've found in the new forums.

Has anyone assembled a comprehensive document for doing repairs across all the models in the various product lines? I got fairly close to having one of everything way back when, which means I'm going to be dealing with a lot of variations. If such a document exists I'd love to use it, else I'll do my best to document my repairs as I go along with whatever resources I find.

And for what it's worth, I'll likely be doing the same with another 20 TI calculators ...

In case you hadn't guessed, this project will probably take a while. But I fondly remember when I got my first ever 41CV from another fellow at microsoft, and I'd write little programs for it before going to bed and I'd sleep great. I won't say "sleep like a baby" because I have a new one (baby) and I slept way better than that. Since my wife and I are just getting started on our family I'm pretty sure I won't be doing any sort of assembly line repairs on calculators. However, I'm really sure that each time I bring a calculator back to life, I'm gonna sleep great!
