I still remember, fondly (sort of) being in a terminal room with 50+
other students all hooked up to a 4MB VAX 780.  The fondness was the
sort of bonding we all had from pulling all nighters to get stuff to
work (this was at UW-Madison, back then it was a hard core hacking
school, lots of Sun's kernel group came from Madison, including 
Rusty (NFS) and Mojo (he wrote the 4.x VM system) and a bunch of 
others).

The not so fond part was hit ^T over and over again (it gave you
a one line PS like output showing load) while your compiled seemed
swapped out forever.

The not fondness made me take out one of the very few loans I have had,
in 1985ish I borrowed $2000 to buy a Okidata CPM machine, it was a lot
slower than the VAX, but all the cycles were mine.  I wrote a lot of
code on that machine.  Including assembler versions of cp, rm, ls, 
etc, each of which fit in 512 bytes because that was one sector on
a floppy disk, I didn't want to wait for more than one sector to 
load.  Fun times.  Now my phone is like 10,000x faster and has 
easily that much more memory.
