Earlier this month the qestion was asked:
"is more valuable a 41cx broken calculator than a good one?"
As the person that purchased the HP-41CX I can let you in on the reasoning. The same seller was also auctioning the following HP-41C parts which I purchased for 122 USd:
1. two HP-41CV boards
2. two HP-41C boards
3. one complete HP-41CV case
4. one complete HP-41C case
5. one half HP-41CV top with a 41CX bottom.
6. one partly diassembled card reader (with all parts)
7. various screws, zebra strips and misc.
Combine this with the HP-41CX not working auction for 98 USd. This calculator in fact was working but had an HP-41C bottom shell and HP-41CX top shell. Also the not working part was the connection between the module i/o block and the keyboard pca. Cleaned the contacts and it is now fully functional.
Also, I have Roger Hills original HP-41C with all the bugs and a bad LCD driver and Gene Wrights HP-41C with all the bugs and a bad ram chip.
After testing the parts auction I now am able to:
- replace Genes Ram chip (which will be returned to the owner)
- replace Rogers LCD panel (which will be returned to the owner)
- repare and rebuild the card reader
- repare and rebuild two HP-41CVs
- repare and rebuild one HP-41C
- swap out the wrong HP-41C shell on the CX with the correct
bottom shell
so for approximately 200 USd I will have:
- six functional HP-41xx's (two being returned as fixed to
their owners.
- a functional card reader.
- some spare parts.
The moral is, sometimes auctions aren't all they appear!
Cheers, Geoff
