I have one of these. I bought it new back in the late 80's, and used it as a C programmer throughout the 90's. It's a great little machine, very useful if you're doing low level bit manipulation. Yes, other advanced calcs support different bases, but the CM-100 is much more convenient to use. Also, being able to set your word size and using signed or unsigned is not supported on most other scientific calcs.
The HP-16C reach level of unobtanium. So when there was possibility, I bought DM-16L from Swiss Micro. And, surprise, surprise, I'm using it. Whenever I'm playing with assembler or directly manipulating hardware on any kind of old or retro micro computer, the DM-16 is best companion. As DM-16 capabilities in standard math are limited I later accompanied it with DM-42 So not daily, however, I'm using both of them.
There is also the JRPN 16C on Android (also a JRPN 15C) by Bill Foote. I worked with Bill to improve the display of the 16C and in my opinion it is now better than the HP original. Also the recently launched HP15C Collector's Edition (hardware calculator) has a 16C 'hidden mode' built in and there is a rubber keyboard overlay available to convert the key legends.
I began my career in the early 80's doing IBM assembly language programming. I also worked on a Z80 based check repair machine. I bought a CM-100 when they first came out. I used mine pretty extensively until I moved to higher level languages later on. It still works fine even thought the case cracked long ago and was epoxied.
I'd love to see a calculator that can do arbitrary base, floating maths, transcental functions, complex etc, all with arbitrary base. I'm sure it's possible!
There's also the "TI LCD Programmer", and its predecessor, the "TI Programmer" which sports the red LEDs. And there is the Programmer II. All of them are pretty darn cheap, and possibly still wildly overpriced. The LCD and "II" versions are dedicated to bit-banging and only has one "shifted" function key (2's compliment, with no obvious way to use it). There's no rotate left/right, and of all things, no apparent way to display in binary. Dec, Hex, & Octal are represented, but not Binary. The original LED version does not have the 2's compliment. I'll break out the manual to see how to use it. But I doubt that I will be impressed. And there is also the DATEXX DS-700 30Xa Plus (or the DS-700 30III) and the DATEXX DS-834 which will do bit operations. And there is the HP16C app for Windows which is what I use. And it's now donationware. But the Casio would get the job done. :)

Not a calculator that I'd ever use myself. That said, I found the demonstration of its functionality to be quite fascinating. Thanks for sharing.
After all my years collecting calculators, I've never come across this one! However, I've noted it uses the exact same case as the fx-115.
Still use my TI-89 when programming but you're right that entering hex and choosing operators is more cumbersome than this calc.

Yes, Wolfram Alpha can do those things I believe. Not sure how useful they are!
@@CalculatorCulture Yes Wolfram can. DC and BC can also do a bit. But as you say, not sure who needs that!

Can you do a video on the Sharp PC 1402. For me Is a great pocket computer
I don’t have one at the moment but I’ll keep an eye out for one.
