TI’s answer to the 41 and peripherals

[Dave Britten]

The TI-88 was originally going to be their alphabetic model, but it doesn't look like it would have compared with the 41 in terms of peripherals and connectivity. For whatever reason, the 88 was canceled shortly before release. They never really had an answer to the 41C.

The TI-95 Procalc came out much later (1986), and it compares very favorably with the 42S, and even surpasses it in a few aspects, such as comparisons between x and any register, the single slot for RAM or ROM expansion, a more readable LCD, and a port for connecting to a printer or mass storage. However, it's also HUGE - probably about 10 times the size of the 42S. It's a very nice machine though, and definitely the best algebraic keystroke programmable out there.

After that, TI kind of veered off in the direction of graphing calculators and the educational market. I think the 85 and 86 were really their last "engineers'" calculators.
