Re: [TUHS] Unix on Zilog Z8000?

… and after Mary Ann was done with it (sometime 1981?), Professor Fabry gave the UCB Onyx to a bunch of undergraduates which they used as the first computer of the Undergraduate Computing Facility (UCF, predecessor to the UCB XCF which had a pile of Suns to play with) in room B50 (basement) of Evans Hall. I was one of those undergrads. That machine became the “x” host on the UCB BerkNet, and it was where B version netnews software was written by Matt Glickman (he was a high school student at the time and while he had Mary Ann’s patronage, my memory is that none of the more official computer services in CS or the Computer Center would give him an account - but we did). At the time, every other computer had restrictions on who could use ‘em, or that you had to pay hefty fees for use (the computer center PDP-11/70s were in that class) - our policy was: if you have a current UCB student ID, we’ll give you an account. We didn’t care whether you were a CS or Engineering student, or not. I remember fixing bugs in various bits of BSD stuff we added to the userland and kernel - we had full source to play with, which was nice. Adding job control was a top priority, and one of our hacks was to change the tty line discipline to restore previous “cooked” character processing state if the program in foreground which had last changed it exited non-zero - that way, programs that modified tty state didn’t need to be recoded for job control too, which, in a system with PDP-11-like memory restrictions (64k text, 64k data maximum per process), was useful. We trained an awful lot of students in the ways of Unix, and many of them became system administrators of the explosion of Unix systems which came to UCB later: the workstation clusters, other microcomputer based Unixes, etc. Kernel hackers (systems programmers) too. Mary Ann also allowed me to photocopy a samizdat copy of the Lions Book, too. I still have that … somewhere, though I bought a copy of the Peter Salus 1996 republication, too. Erik Fair
