Yes, we had a /780 with only 256 KB of memory. One Friday
afternoon after the service
window would have been closed by the time somebody could get
out to our
location, a memory board died. I diagnosed the problem, and
pulled one of the
memory boards. Wrong one, pulled the other one, and the
machine came back
up. One of our users had a BIG batch job to run over the
weekend, a huge
finite element simulation. Well, amazingly it ran on 128 KB
of memory!
