Yeah, I've been into the RPN thing for quite some time.
Favorite?
The 35S sits by the CNC machining center inside a zip-loc bag to keep oil and metal shavings off of it.
Desk-side is mostly the 41CX.
One of the things nobody has mentioned yet is how much better the 41's LCD display is when compared to ALL other HP calculators, excluding Prime. I tend to do a lot of coding and CAD work under subdued lighting. The 41's display is very easy to see just with the monitor's illumination. The other's suffer from low contrast LCD's that are hard to see outside bright office environments. Prime is self lit so that's not a problem.
I had a couple of others but gave them away. One was an HP-50g and the other was a folding model, just can't remember the model number. Yeah, HP has made some, well, less than great calculators.
- Zombieball 11y agoI did a bit of research about the 41c after reading your endorsement. It seems they also had plugable ROM modules you could buy loaded with various functions and programs! Do you happen to have any? I'm curious to hear what your opinion of them is.
- rebootthesystem 11y agoYes, I do. I'd have to dig them up but I remember a mechanical design module as well as an electrical design module. You could also plug in other things into those ports. I have a magnetic card reader that was used to save and load your programs. There's also a little printer and an expanded I/O interface. I haven't looked at some of this stuff in years.
