41CX, I will try to find the site I got it from. I bought an -hp- 31
on an employee discount when they first came out. Sent it back for an
update and repair and used it all the time until a burglar got it. I
learned the RPN before using a conventional calculator and find it
easier to use since one does not have to juggle parentheses and
registers. I've looked for used 41s but they are too rich for my blood.

P.S. I have all my old slide rules from my wooden Versalog to the laterI just checked and I have 9 including the old Accu-Math that I got in maybe 5th
plastic models. Along the way, I've also collected a few more for fun.
In fairness, I've also reacquired (and made work) every model of
HP calculator I ever owned. Wait ... I'm starting to see a pattern here.
The past isn't what it used to be ...
or 6th grade. Somewhere I'm thinking there is a circular one hiding also.

and a 32SII. I’d love to get a circular slide rule.
