Yes. AFAIK, the HP-16C is unique among calculators with base conversion,
in that it supports unsigned, ones complement, and twos complement
arithmetic on a word size adjustable from one to sixty four bits. And
it has all the logical operations, shifts and rotates, etc.

Many other calculators have some simple base conversion functions, but
not that compare with the HP-16C.

Of course, on a programmable calculator you could implement a lot of
that yourself if you had to, but with the HP-16C it's built in. Jake
Schwartz has written a good 16C simulator for the HP-48, but I haven't
seen any other good ones.

The HP-41CX is essentially a 41CV with the HP 82180A Extended Function
Module and HP 82182A Time Module built in. They added some additional
functions as well. Unfortunately they did NOT build the equivalent of
two HP 82181A Extended Memory Modules into it; many people wired them
in themselves.

At first I thought you were referring to the TI SR-52 programmable
calculator from the mid-1970s, which didn't have such things. But
on reading the rest of your message I realize that the TI-52 must be a
different calculator, presumably with an LCD display.
