I remember PUFFT--that was Saul Rosen's baby, wasn't it? A FORTRAN for
undergrads--put in anything that *resembled* a FORTRAN statement and get
some sort of result. Missing parentheses? Misspelling? Outright
syntax errors? No problem. I think Purdue had two 709x systems for
PUFFT The CDC 6500 was reserved for Serious Work.
I understand that at the time, 7090/7094's were comparatively plentiful
and (comparatively) inexpensive, hence their use.

Neil had a lot of interesting stories about the ETA-10 (originally named
the GF-10 for the target of 10 gigaflops). It all seemed so fantastic
Ah, it's all fun...
