I have opened many HP41C/CV/CX's but I have never seen one without the PCB board. I just opened one with the PCB board built into the key/display board. Has anyone ever seen this? If anyone would like to see a picture let me know.

That's neat! I haven't heard anything about these. Is it a CX? What is the Serial Number?

Dear Ty, That looks really neat! You said this is a C, so is it possible that this unit was originally a Fullnut C that was sent in to HP to be fixed, and they upgraded it to the Halfnut C equivalent? That would make it very rare. Is the screen rounded or squared off at the corners? I mention this because a CX Halfnut that I have looks a lot like your picture, but it has a bigger chip. I would love to see a picture of the front of your C. Where did you find this thing, by the way? Best regards,

Ion, A picture of the front has been posted. As you can see in the picture the display is rounded. I got it on Ebay. I guess it was repaired by the way the serial no. has been scratched in on the back. Who knows.

The last one I just had one of these in a CV variety. My guess is that this is simply reduced electronic versions. I don't think they are all that rare. ▼

So do we now have the full-nut, half-nut, and the no-nuts? Now I've got more to collect. How about blank-nuts, half-blank-nuts and no-blank-nuts? I'm going nuts just thinking about.

Another late follow-up - I just don't find the time to keep up here :-( Ty's No-Nut is definitely from an HP-41C sent for repair to HP, who replaced the entire calculator with a Halfnut unit and scratched on the serial number of the original HP-41C sent for repair. These _are_ rare - the HP-41C was no longer on sale when the Halfnut version of the HP-41CV and HP-41CX was put on sale. So the only way to get a Halfnut HP-41C is to find one of these replacements. How many people will admit to having one? I was extremely lucky to get one froma fellow collector to whom I am very grateful! Wlodek Mier-Jedrzejowicz ▼

It sounds like a 41C that I had sent back to HP for repair in the mid 80's. It came back with the brains and memory of a 41CV (and a note not use use memory modules). Case still says 41C and has the original serial number. I wonder what other mutants are out there? |
