Questions about and problems with HP calculators
The hp
forum can usually answer questions far faster than I can. The forum is
read by hundreds of HP calculator users each day. You may also wish to browse
the
articles
forum for detailed help and repair articles. If you ask me a question
about your calculator, it might take several weeks for a response. I don't
use all models regularly but on the forum, someone uses every calculator.

Repairs: DIY and services
Please see the repairs and batteries
page. There are additional repair articles in
articles
forum. If you can't find your answer there, please post a question in
the hp
forum. Several regular readers of the forum know much more about repairs
than I do. The Museum itself does not have a repair service.

Manuals and Instructions
Most HP manuals are available on CD-ROM or DVD-ROM. Please visit the
CD order page. The CDs
and DVDs may be printed or viewed on-screen. All of the instructions that
I have for HP calculators are on the website or the
CDs. You may order the entire set (hundreds
of manuals) or a single CD.
I'm sorry but I have no instructions for non-HP calculators beyond what is written on the website.

Value / Price
For HPs, please see the
collector's corner.
For non-HPs, I'm sorry but I don't know. Though I have an assortment of older
calculating machines in the museum, these were picked up at very low cost
in the mid 1990s. I have no idea what they might be worth now.

Question about a non-HP calculator
Everything I know about non-HP calculators is currently on the website. Sorry.

Earlier serial number
Many people who email make the mistake of comparing the right-most digits
on the their calculator (the sequence number) to the digits listed in the
collector's corner.
Please verify that you are comparing the left-most digits (ie the
date code portion) to the numbers shown. If your left-most digits are earlier,
please contact me. For example, if the digits
listed in the
collector's corner
are 2338 and your calculator has the serial number 2411S01310, then your
calculator is a later sample.
