Hi Mike.  Thanks for chiming in.  The system was functional by the time 
I joined the project.  I merely developed some user and system 
documentation.  (Learned a lot about o/s design from the exercise.)

I'd heard that the hardware had general problems, not just at UCLA, but 
that UCLA uncovered them sooner than most places, due to the way the o/s 
stressed the hardware.  Probably had to do with the paging (or was it 
mapping or was it...? ) mechanism.
