Most mind-blowing program for your favorite calculator

[John Garza (3665)]

For me it would have to be the humongous Star Trek programs attempted on 70's era machines. "Star Trek Advanced" for the HP-67 in 3-D space no less. And the TI-59 Star Trek game that took IIRC 13 mag cards and was essentially the same as the various Trek games in BASIC at the time.

Personally, I'm a strong proponent of 'use the right tool for the job' philosophy. So I never really saw these as more than just an intellectual exercise. If I wanted to write a similar program, I would have used MS BASIC on an Altair or something similar in those days.
