DEC 3000 Model 500 Home...won't boot. It had had DEC
UNIX on it
OK. I *think* Ultrix was the only OS commercially available (not
sure
about the later product named "Digital Unix" that was formerly OSF/1)
No, Ultrix was only available for the PDP-11, VAX, and MIPS. On Alpha,
they went from OSF/1 to Digital Unix to Tru64.
AFAIK, your box has a MIPS CPU, not Alpha.
You must be thinking of a DECstation. That's an entirely different beast.
