Yep! Message #17 Posted by geoff quickfall on 26 Feb 2010, 8:15 p.m., in response to message #16 by Gerry Schultz
In fact I have section in the appendix for memory module combination "double x-memory". Restoring different battery packs.
The HP41 peripheral section could be a book on its own. So other than the card reader, calculators, memory upgrades, battery packs and a few other sections such as heat stake replacement/repairs, I think the peripherals will have to wait.
Take a look a Mathias site for the number of HP41 peripherals there are!!
I will be restoring a GEODAT 126 in the appendix which may help people get into other types.
Yep, THAT book would easily be 500 pages on its own!!
So far the logistics entails finding a representative of each family, some peripherals, memory upgrades and etc and then actually doing/documenting each repair.
Peripherals would be fun and I do have the following HP41 peripheral which could be included but I think the calculators will be the focus for HCC2010:
HPIL printer
HPIL plotter
Non HPIL printer
Infared printer
HPIL tape drive
HPIL floppy drive
LASER wand
6 card readers
As it is I have included and completed the following restorations and upgrades:
HP65 complete restoration
HP45 quartz crystal upgrade
HP55 quartz crystal replacement
Classic series LED block replacement as an example of unsoldering.
HP29C complete restoration
Woodstock battery modifications
HP97 complete restoration including card reader and printer

capacitor and possible an LED block swap

As you can see a lot of work and photography. I think peripherals not covered would indeed fit in a book on its own. Having said that, the title is HP Calculators (with some extras).
My wife is renovating the house, I am restoring my 1973 Celica from the ground up, work and the book so pretty busy here for the time being. Company just called and now off to Hong Kong tomorrow.
Work, work, work!!! Of course during my first 3 hour break I will work on the book on my laptop.
Cheers, all!
