4 BSD

Logging into a 4 BSD system
Type: Multitasking, multiuser
Creator: CSRG
Architecture: VAX, theoretically portable
Current Version: 4.0 (1980)
Year Introduced: 1980


4.0 BSD improves upon the 3 BSD release with curses, better job control, csh, and "reliable signals"..

How do I get this to run?!

You can follow the guide Installing 4.0 BSD on SIMH, which was derived from the excellent work of Naoki Hamada here for more information.

There is also the historical document Setting up the Fourth Berkeley Software Tape.

Currently if you enable the dz ttys you'll get a bunch of 'ZERO VECTOR UBA RESET: dz up 'errors... So this isn't very usfull if you were hoping for some kind of multi user system. The only 'good' thing is the 32v idle in simh-3.8-0 works well on this version.

What Runs?

Not very much.... 4 BSD does not provide any modern networking, and the C compiler is far from ANSI. Also keep in mind that 4 BSD does *NOT* include any TCP/IP networking... It's worth noting that the zork binary made it's appearence in this version of BSD Unix..
