Texas Instruments TI-60
Oh, no, not again! Another "almost programmable"! These calculators drive me nuts. They're nice, useful, accurate, and ergonomic... what on Earth possessed the designers at Texas Instruments to not include a GOTO and a conditional instruction? About the only reason I can think of is marketing: they probably didn't want to jeopardize the market of their higher-end programmable calculators.
The TI-60 (not to be confused with the SR-60, also from Texas Instruments) looks and feels very much like the TI-55-II or TI-55-III. Indeed, any differences are superficial, except that the TI-60 has about twice the amount of memory of the LCD TI-55s. Unfortunately, the completely unmerged programming model makes this larger program memory less useful than it could be. I have not, for instance, found a way to shoehorn a reasonable approximation of the Gamma function into this calculator.
One good thing: this calculator's RST button, when used in a program, does not stop program execution; instead, execution continues at step 0, so rudimentary loops are possible, just like on the original (LED display) TI-55. As an example, here again is a simple factorial implementation. When the calculation is complete, the program stops with an error, and the result can be recalled from memory register 0:
