Question about HP-41C Serial # - Daniel - 11-08-2005 I recently bought a nice 41C which serial number begins with 2043A. Re: Question about HP-41C Serial # - Randy - 11-08-2005 No, they (half-nuts) did not appear until 1985 or so. What you have is a unit that was returned for repair late in the game, after they stopped fullnut support so HP service just stuck the old back on a new front half of a replacement calculator.
It would be interesting to know if it truly has only 46 free registers or if it is really a CV with a C label on it.
Re: Question about HP-41C Serial # - Daniel - 11-08-2005 46 reg free. Re: Question about HP-41C Serial # - Howard Owen - 11-08-2005 Hmm. So either they made some halfnut 41Cs specifically for replacements like this, or else they hacked a 41CV to make it act like a 41C. And what HP hacketh, perhaps ..
Halfnut 41c - Gene - 11-08-2005 I believe Wlodek's guide to HP's says that HP made a very small number of halfnut 41c calculators for replacements.
They are quite hard to find and worth $$ to collectors who truly want one of everything.
Re: Halfnut 41c - Randy - 11-08-2005 Sorry, forgot to add that since a CV defaults to 46 free, you've got to do an [xeq] [alpha] [size] [alpha] [000] to know for sure. Chances are it is a HP hacked C version of a halfnut CV. Several have been reported here and yes, the gold ball contacts are consistent with an early C case back. Consider yourself lucky, it still remains the only 41 variant I do not own along with many other 41 collectors, marble blue and clear cases non-withstanding.
