Texas Galaxy 67: A fragile yet powerful beast from the 90's

[Gene]

The TI 67 (and its younger sibling the TI 65) were both good TI landscape models. The 67 had up to 1500+ program steps or 90 memories. The 65 had 100 steps or 16 memories. So in this regard, the 67 is much to be preferred.

I also like the TI-66 except that it is terribly SLOW ugh. It had up to 512 program steps. It is often cheaper than a 65 or 67 so it's the one I have lying about to play with.
