Nice to see someone is collecting some "real computers". I have some
microfiche on the PDP8 and if you can tell me the power supply model
number, I may be able to look up the transformer voltages for you...

Interesting collection. I had not realized that DSD made a controller for the
PDP8, just for the PDP-11. Also I am really surprised that DEC made
an RL01 controller for the PDP8.
AS for your VT100, it sounds like you might have a VT103 which was a standard
DEC product. Does it use a dual 11/23 but have added a 3rd party MFM controller
with its own boot ROM or are you using a quad 11/23 and an RQDX1?
In my case, I used a Sigma RQD11-B controller that I borrowed for a while
(too expensive at the time) with a dual 11/23, M8059 memory (1/4 MByte)
and a DLV11-J. The ST412 was placed INSIDE the VT100 under the tube.
Later, the backplane was upgraded to 22 bits, a 4 MByte memory substituted
along with a dual 11/73 and a Sigma RQD11-EC ESDI controller. In this
case, the drives were outside running on a PC power supply. A DHV11
was also added. This system was only used as a demo a few times since
the power consumption of the 5 boards was too high for the VT103 to
take a chance. But having 10 others terminals and a printer hanging off the
VT103 and 2.4 GBytes of disk space in the back was rather impressive
just for the fun of the experiment.
By the way, all this was running RT-11/TSX-PLUS. I have a friend who
may be getting rid of his PDP-11 systems and there are probably some
RT-11 manuals. But they are heavy. The shipping would be expensive.
And he may want some payment, especially for the SCSI host adapter -
Peter Turnbull are you interested?
Also, I am not surprised, but no one seems to consider software as part
of their collection. Is it because they are mostly copies that have been
"acquired" or because software is not really considered collectable by
most list participants? From my point of view, the software is far more
important since eventually (100 years?, 200 years?) the hardware will
not be able to be repaired, but the software should always be able to
run under an emulator. For the PDP-11, I use the emulator 90% of
the time at this point since I don't need to switch systems plus the emulator
runs 3 times as fast as the actual DEC 11/83 hardware even under a
Pentium 166 MMX. When I finally upgrade the PC to a 1 GHz system
in a few years (assuming that I can still run W95/W98), the difference
will be even greater.
Does anyone on the list run RT-11 still other than Megan Gentry?
Do you tinker with the operating system code at all? Does anyone
care about the RT-11 Operating System?
Sincerely yours,
Jerome Fine

It was probably a Wang 2200 PCS. The PCS-II was similar, except that it
didn't have the integral cassette drive and instead had a pair of 5.25"
floppies on top that were really ugly. It might have been one of the WCS
models (WCS/10 or WCS/20) but I'm not very familiar with those to know how
they were different from the PCS.
I learned to program on a PCS with 8KB of RAM. It is my #1 wish list, and
I've actively been looking for a couple of years.
You can find some links on my nascent Wang web site at:
http://www.thebattles.net/wang/wang.html
In particular, there is a picture of a PCS-II here:
http://www.gaby.de/ewang.htm
Check out the two subordinate pages that I've written that compare Wang
BASIC to MS BASIC and that lists which CPU models had which BASIC
statements. I hope it brings back some memories for you -- it did for me!
I have a fantasy of writing an emulator for the 2200, but I don't know if
it will be practical without schematics, as the 2200 used a microcoded TTL CPU.

Are you _sure_ you don't already have a PCS? Maybe it's tucked away behind
Woz and the shrinkwrapped Cray :-)

For some reason I've stuck with a bunch of DEC stuff, and mostly q-bus.

VAX 4000/90 (BA??)
MIPS
DECStation 5000/240
DECStation 3100
DECSystem 5500 (BA213)
PDP-11
PDP-11/34a Industrial (RL11 + RLO2)
PDP-11/34a Corporatate (TU60 + parallel I/O)
PDP-11/23 (BA23, RX02, RL02, corporate rack)
PDP-11/73 (in a 11/23 chassis :-)
PDP-11/02 (BA23)
PDP-8
PDP-8/e 4K, short box
PDP-8/f 24K, long box (8/e box really, with FPU)
PDP-8/m (two of these, both short box)
I'm in the process of putting together and 'blueprinting' my VAXen so that
I can store them more efficiently with all their components.
The MIPS stuff is available for trade but the 5500 may be spoken for.

The RL8A. I got one back in college because I couldn't find an RK8E for
even twice the price, and RL01 drives were going for <$100 (plus shipping,
natch). It maps the 5Mb disk to two primary virtual devices and to a third,
smaller, slower virtual device. There is also an RL02 handler which maps the
10Mb to, I think, five virtual devices, but I've never run it.
There is also an optional RL02 controller for the DECmate I, but I've never
seen it. My DECmate has the floppy controller and a single cable (DC37->DB25),
but there is a Y cable that will let you run two sets of RX02 drives. You can
even fit both sets in the DECmate pedestal, but I've never bothered to try. I
have a couple of table-top RX02 enclosures that do nicely.

Not lately, but I used to. I never tinkered much with the OS, just wrote
some stuff in MACRO and played the games.
