Full Version: How'd the Woodstock C's survive?

Hi all.

After my own 29C bought at auction and perusing this site, I now realize that recharging the 25C and 29C would cause these calcs to be lobotomized beyond functionality because of the charging damage. But, how was it that the original 1970s owners would still have a functioning 25C or 29C?

Thanks

They can be recharged no problem. They are only damaged if you operate them from wall power without a battery, or with a defective battery.
Well, I'm stumped! Not certain why my constant memory has been affected. But, the Cs I bought at auction have been having constant memory loss. Another glitch is that only the first 40ish program steps remain intact on my 29C after I key in a program while the 29C is turned on.

The HP-29C has two RAM chips for storing its 98 program steps. If only 49 steps can be used it indicates the second RAM chip is defective.

Thanks for the insight. Do you think I should send my 29C to Randy at Fix That Calc?
Is Randy back? See this thread.
Sorry. Natural reflex. Besides, I haven't needed repair for a while. So, it's been years since I checked in with my contacts. Thanks for correcting my mixup.

Hi Matthias,

All fine here. There is some new stuff in the queue, but not yet time to reveal. Needs some more weeks. Smile

For everyone: Woodstock rebirth centre can be found here
