> One of its prominent characteristics was charging for everything. Say you'd log on, run the command to get into the forums. When logging off, it'd tell you how much your account had been charged for CPU time, storage time, etc.

Yep, it sure did. I used it when I was there for my assembly language class. I remember my roommate used up his entire allotment of CPU time in one run where he accidentally had an infinite loop. (If I recall we were only allowed something like a few seconds of CPU time for the entire semester. It was typically all you needed.) He had a large print out about 50 pages long that said nothing but “The value of a is now 1,” over and over again. Luckily you could just tell the professor and he’d give you more time.
