After 30 years or so, I gave my TI-36X solar calculator a [too] hard drop and now I'm missing a few segments. :(
From http://www.datamath.org/Sci/Mode...
Texas Instruments changed in 1996 the design of the scientific calculators to a smoother design and replaced the TI-35X and TI-36X SOLAR models. ...
For occasional desktop use, its importance to me is the hexadecimal feature. So when deciphering AVR "memory dumps" I can put it into hex mode and then convert back-and-forth with base 10.
Now, there is the TI-36X Pro replacement at a reasonable price. But the hex feature is multiplexed with the regualr keypad so a mode change needed with each digit entry (I assume):
I found the Casio fx-115ES Plus that is inexpensive and appears to have a hex mode:
Any other suggestions?
