Texas TI-66 Programmable: Toshiba skills to rescue Texas...

[Pierre]

I just read this topic with interest but also very surprised.
I own a TI-66 and its printer and this calculator has been a big disappointment for me.
Indeed, a former follower and fan of TI-58C, I expected to find a worthy successor to the old TI... but apart from the alphanumeric display of instructions...
no plug-in modules, and no more "cheating" possible.
The hidden HIR function had however gained many followers.
For slowness, simply turn the 2 “6”s a quarter turn to the left to imagine 2 snails racing.
Above all, I would have liked the expected marketing of the TI-88 but unfortunately...
So I made up for it with the HP-41 (c/cv/cx) and some peripherals !
(despite my collection of TI calculators)
