While performing website maintenance tasks, I discovered that I had the HP41CL as “not available” and therefore it could not be ordered. I have fixed it and now it can be purchased again.
Be aware that we can also perform conversions. That is, if you have a HP41C that has been with you a long time, is in working condition and has square screen corners, you may consider taking it to surgery. This surgery is not cosmetic at all - oftentimes you won’t be able to distinguish one from another, unless you have ordered it with serial cable. We perform that modification for 450 €, or 486 if you want the serial cable and connector fitted too.
We have also a gorgeous unit with original box and manuals. It is more expensive - but you cannot have better.
