I remember a microVax that I used as an undergrad that had a real teletype set up as the (serial) console. Had the effect of (a) rebooting the machine if it was ever accidentally turned off, and (b) halting the machine whenever it ran out of paper. I was always amazed that the Ultrix would keep going as though nothing had happened as soon as more paper was loaded and it was put back on line.

Nothing tops the feeling when a bugcheck on vax/vms system causes all these hex dumps to be printed slowly and noisily to the paper of your hardcopy console. Physical printout and slowness signifies importance while stackdumps with hex values signify secret knowledge. This is not for mortals.

Oh, and of course everybody had to wait for you, while you carefully read through the secret scripture, which nobody but you could understand, until you decide to enter "b <ret>", which initiated thr printing of another few pages of startup messages during the next 10 minutes :-)
