Way back in '77 (I think), I got a mailing from TI advertising and
offerring for sale the TI Programmer, which was a simple 4-function
calculator in that standard black-plastic format they used to use,
replete with the also-standard LEDs. However, it wasn't actually a
four-function calculator, because it included radix conversion and
several standard logical operators.
At home, when I need radix conversion, instead of the Casio Fx-115m or
the Calc accessory, I still reach for the TI Programmer...
