Peanut Gallery Commentary on the Staff Log of Bannings and such like.

I remain a fan of the HP41 series.  I have several in working condition, and 2 that have been custom modified.  I don't have the emulator App for cell phone yet, I'm looking at a new cell phone soon, and figure that can wait.

I'm not sure what happened to mine. I'm pretty sure I still had it when last moving. But somehow it seems to have been lost on the way.

It might be worth some effort to locate. They are hot on Ebay these days.  Turns out there were some manufacturing variations over the years and some turn out to be very rare and more desirable to collectors.

There were 'halfnuts' and 'fullnuts' (also known as 'coconuts') and 'blanknuts' made, apparently of all 3 models, C, CV, and CX. There were also early HP41C models with slightly taller keys.  I have one, and it is an interesting variation.

The accessories can be valuable too.  If you have a wand, it might be worth more than the calculator.  Curiously, the HPIL cassette drives are offered on Ebay for high prices even though functionally, they are kinda useless, the data tapes aren't made anymore, and there has been tape pressure pad deterioration in all the tapes made originally.  Even the QRCs have value.  Directions, accessory catalogs, Application pacs, origianl boxes, are all going on Ebay for surprising prices.

If you have an unusual ROM module it could be very valuable.  I just paid nearly $200 for a Time Module and well over $100 for a Plotter ROM.

No comparable sales on my custom modified CX, but I think a serious collector would go up to $1000 for it.

Hope you didn't leave any batteries in yours.  When they start leaking they can do some serious damage.  They can be fixed, but it can be a pain.  Even dead HP41s have value for parts.  82166 interfaces are worth quite a bit, PPC ROMS fetch high prices, and having the manual for that really helps too.
