I've also found a RF72 drive. I first thought it was a RD54 but on closer
inspection
it turns out to be a RF72. What i've read is that it has a capacity of 1GB
and needs an
DSSI-controller
Can any one tell me what DSSI is and if there exists a DSSI-controller for
a uVAX II ?
I Don't know if the beast is still in working order but I'm curious anyway.

Sorry about this, but I was corresponding with Bill about some
items and haven't heard from him since the 21st....just wondering if
he was having email difficulties or hardware problems....
Thanks.

Ah! That _is_ an improvement. I only have core on my 11/20 (unrestored)
and 11/05 (similarly unrestored). All of my working PDP-11s are MOS-based.

Since Anthony Clifton volunteered to drive to minneapolis and grab virtually
al of the small VAX stuff that i mentioned yesterday, i'll just let him
have the stuff (assuming thats ok with the professor who is disposing
of the stuff).
Thanks for your interest, and i'll keep posting if i find more stuff that
i dont want or need.

Which style is it? One style has disks above and below the CPU (11/730-Z?),
the other has the CPU in something that's more like a BA-11 with the TU-58
at the top of the rack. I have one of the ultra-cramped ones with the CPU
in the middle. I don't have one with the CPU at the top.

Umm... sure. _That's_ an improvement.

How many of these are floating around these days? Serious question, no
smiley. I have two PDP-11/70s, both with, I assume, MK11 boxes and am
interested in low-power alternatives for memory.

In _my_ case, power is the issue. I have a 60A circuit for the entire
outbuilding that houses my larger stuff, none of which is powered on
at the moment. I need to wire up a 30A Hubble Twist-n-lock outlet so
I can plug in either an 11/750 or an 11/70 out there, but once I do,
I'll be interested in firing up one of the beasts.
Just so I'm not making a serious assumtion here, an MK11 is the high-
density memory cabinet for the 11/70, right? What I have is an entire
H960 rack with one BA-11 that houses 16 256K boards (mess-o-4116 DRAMs)
and some incidental memory controller cards. Do I have what I think
I have?

Probably pretty difficult to find.

The "original" MK11 goes up to 1 Mbyte in a box, according to my books.
It certainly was common to see them upgraded in the field to the configuration
that you have, though I don't know what the official DEC designation for
the high-density version was.

Yeah, but there are many places in the US where it is essentially illegal
to hook your own cable descrambler to the cable line, not too much different
than the old Bell System limits on third-party equipment hooked to phone
lines.
There are some attractions to cheap and uniform guaranteed service for
all, but I don't think I want Internet access to become the monopoly
that phone service used to be or cable service is today. It's bad enough
with some ISP's threatening that they only support Microsoft Windows
and that if you've got trouble accessing their service from any other
OS you're out of luck.
Actually DSL from some companies is already worse than that - you have
to have a PCI-bus PC-clone running Windows to use their service,
because the only interface device that will work requires that
hardware configuration and the only drivers available are for
MS-Windows.

The closest I've come is photographing the one at the Deutches Museum on
my recent trip to visit Hans.

John,
I have VAX C also if that would help... I'd offer you OS/32 C, but I don't
think you have an Interdata/Perkin-Elmer/Concurrent, heh.
