I don't know what variety you got, but the R80
(RB80) in the rack with some
VAX-11/730's is a cheap and easy disk to use. Slow, but supported. I
have one in storage. The 11/730 is the slowest UNIBUS machine made (along
with the 11/725, same CPU, different box), .3 to .4 VUPs (the 11/780 and
MicroVAX II are the benchmark, about 1 VUP). You can't officially extend the
UNIBUS, but unofficially, I have attached a BA11 to a 730. It works, but
there are no shielded cables to stay FCC compliant with.
Just a few notes: The VUP is based on the speed of the 11/780 alone. The MicroVAX II is
0.9 VUP.
It will also run Ultrix (BSD UNIX). I recommend an
old version, say, 1.1.
Um... Ultrix is NOT BSD Unix. You may only have been saying that they're similar,
however....
We always used a tu80 on our 11/730. There are other
drives you can use,
but that was the cheapest way for us to go.
Best way to go: Find a Unibus SCSI controller. Rare, expensive, but well worth the cost.
