After about 35 years of use, my TI Programmer II hexadecimal calculator stopped working. It sure was nice for doing hex math, boolean operations, and base conversions. I found an unbranded scientific calculator at the dollar store and it has hex -- and cost only $1. Unfortunately, the characters A-F are printed in dark red on a dark brown case and are nearly impossible to see. Any recommendations on a replacement?

an old HP16c but it's pricey ...
if you have a smartphone, ios or android, you have a lot of hp emulators available for around $5

See this recent thread:
https://www.eevblog.com/forum/reviews/scientific-calculators/ (https://www.eevblog.com/forum/reviews/scientific-calculators/)
If you grab the "higher end" scientific calculators from TI or Casio (see the references in the thread), they have a hex mode.
Count on ~$20.
Alternative is to use a smartphone with the right app (also see thread).

HP16C...
I got it so long ago I forgot exactly how long. (30+ years)
The number 4 key is slightly off (not the same feel as other keys, needs firmer press) but otherwise still works like a charm. I forgot how long ago it was when I had to change battery, or if I have even had to change battery at all.
I have the 16C emulator running on Zenfone2e. It works rather well but since it lacks real key-feel, I don't use that much.

SwissMicros make an almost-clone of the HP 16C.

Look for the DM16L. The display isn't as nice as the HP original, but it works.

After looking at various options, I decided to try a smartphone app, CALC-P. I like it. It has separate number keys for separate bases. So I can actually enter hex, decimal, and binary at the same time. For example, I can enter a number in hex and divide it by a number in base 10. It shows the entries and results in all three bases simultaneously. And, being free, the price was great!
