I remember way back in 1990 when I first got to my university, salivating at the idea of getting access to their Cray-2. It had been paid for by the DOE for a research lab, and basically nobody got access to it. It took me three years to work my way up the computing center ladder, but I was finally able to get an account on it through connections.
UNICOS was weird, and the interactive shell was slow as molasses. But it sure ran my raytracing jobs a heck of a lot faster than a Sparcstation 5!

Essentially they were batch Fortran machines, CDC6600+++ with larger memories with modern-ish OS hacked onto them.
