The focus pot is part of the flyback as is the HV adjust. I believe the
Yoke
is bonded on that tube so movement is unlikely.

Same way you would for floppy only slower.
I'd make a bootable floppy first and put the DU/MU drivers
on it plus anything else you need as RX50 is has enough room for
a useable system. Then I think, you need DUP and BUP on there.
I have the capability but I backup to RL02 as it's much faster.
Also that RD54 (159mb) will likely be partitioned into 5 drives
as RT-11 can only address up to 32mb disks.

Jay, the email address for me is changed. I was getting burried in
UCE/SPAM
so the replacement is kb1gmx(a)qsl.net.

Easy run INIT the target disk and run standalone backup with /image

details.

We spent a lot of time testing the classiccmp mailing list - couldn't find a
single problem. There were one or two people who said they were getting the
digests twice, but they never gave me details. The only thing I can think
of, is that they were having problems with their pop mail session to their
ISP? If you start to download your mailbox of say 50 messages, and the
connection is lost (not the internet connection, but the pop session), the
server will re-transmit the entire batch so you'll keep getting those
messages over again until a complete sucessful download occurs - then it
will mark them as deleted on the server end. Again, this would be an issue
with the ISP, not us. If anyone still has problems or can supply further
details, please let me know.
Several bugs were found in the list archives at www.classiccmp.org and these
have all been fixed to the best of my knowledge. If anyone sees anything
further, please let me know asap.

I thought I mentioned BUP, yes it did.

Browsing the surplus stores today - came across three things I don't have
any interest in... maybe someone does - if so, email me.
Calcomp 1034 (Or was it 1038?) plotter. This thing is BIG. Appears to be in
good cosmetic shape, have no idea if it works or not.
AT&T PC 6300
Something called an AT&T 6386 (or something like that) WGS. Noticed a few
recent posts on the list about this machine too.

Y'all might want to wander over to alt.tasteless and look for a thread
titled something like "Near Ape Shit At Work Today". Seems someone
did not like his Mac being replaced and so attacked the EDS staffer(s)
who came to do the deed with a hacksaw. However he was not
successful.

I'm sure there are VME cards. Dunno about ISA.
I've posted the pinout for the 2 x 50-way interface on my website at
http://www.dunnington.u-net.com/public/pertec.ps. It's a PostScript file.
I can't remember where the information originally came from, it was either
an Emulex TC02 manual or the manual for my tape deck.

The 9000/500 may have been a commercial failure, but HP learned a lot
>from it -- its I/O bus (later known as CIO I think) was adopted by the
PA-RISC 9000/800 (and 3000/900) machines. I expect this meant the
machines had trade-in value for their I/O cards (as well as the gold
and copper in the CPU, IOP, and memory cards, which are all
surprisingly heavy from the copper core and shiny from the
characteristic HP gold plating).
The packaging is interesting, especially on the CPU/IOP/memory cards:
the boards don't have sockets for the ICs. Instead, there is a cavity
in the non-conductive board material, exposing the copper sheet at the
core of the board. The IC substrate is bound to this copper core, and
its bond-out wires are soldered to the traces on the board. Then a
lid is fitted over the cavity(ies) to protect the ICs and bond-out
wires. This was done to carry heat away from the ICs, which ran from
a 16MHz clock and did a pretty good job of turning electricity into
heat.
It was also HP's first entry into the Unix market. The 520 could also
be a BASIC workstation (a high-powered multiprocessor replacement for
the 9845!) but I have not seen any configured that way.
It was also HP's last big stack machine, or at least the last one
that made it to market. (Maybe Lee Courtney can tell us more about
Vision.)
HP contracted with The Wollongong Group to provide TCP/IP transport
and application software for HP-UX v5 on these in the mid-to-late
1980s. I started working at TWG in 1989, by which time engineering
support for the product was over, and soon found that from their point
of view, 9000s and 3000s were all the same and so I got to support
that product as well. That was my first introduction to it.
Then I found the FOCUS machine instruction set manual in TWG's
library. Oh my. It's a 32-bit stack machine, sort of a big 3000.
Oh my.
Then I got to investigating a remsh crash that took me deep into the
kernel. That was how I became a TCP/IP stack internals kind of guy.
My memories are dim and distant (TWG ended support for the 9000/500s
in early 1994 I think, due to no sales and no contract renewals), but
most of the customers I talked to were either US military or
contractors.
Its Unix port has some oddities. It was ported on top of another HP
OS called SUNOS that provided low-level generic services to both BASIC
and HP-UX, and the AT&T filesystem was layered on top of an HP
filesystem structure called Structured Directory Format or SDF. SDF
makes itself visible by the absence of . and .. in directories -- ls
and open() will fake them as needed, but if your code opens the
directory and reads it they aren't there!
I don't think it has the concept of partitioning a disc into multiple
filesystems: one disc volume is one filesystem, no way around it.
Swap space is taken as needed from whatever free space is available on
at least the / volume, maybe others too. Strange but nice in its own
way.
