These are incredibly common, most libraries will have them. The printing
process is either mimeo (alcohol) or the diazo process used for
blueprints (ammonia). I have only seen one that used a toner type
photostat process.

I had some of those. They were wire-wrapped onto printed circuit
boards which were mounted in lightweight alloy chassis, all made at
Ferranti, supposedly for or from the TSR2.

Jay,
it would be of great help, if somebody could scan the documents of the CDC drives.
I own four of these beasts and neither don't know to configure them nor to repair them due to the lack of printsets.
And I'm surely not the only one out there.

Pierre

Hi
Anyone have any info on an 8" hard drive + 8" floppy combo which
appears to be an "SMS FWD 0101"?
I believe this was used with a qbus system. I don't have the controller
card however, just the box and a 50 pin cable :-)
The floppy looks like 8" double sided. The HD is 8" (been a while since
I've seen one of those).
I'd love to find the mating QBUS controller card.
The large card on top of the hd & floppy appears to have an 2901 and
an 8085 as well as other fun chips.
(I just gotta stop clicking on those blue underlined words ;-)

If someone can mail me a sample of the "mold" I've found a place that will
test it.
You can mail it to:

Thanks!

I am considering using two modern +5v at 25A switching power supplies to
replace the +5V source ( leaving the original -5V at 2A,+15 at 2A,-15 at 2A,and
+20 at 4A as original) in a PDP-8A.
My intent is to increase the reliability of the system. I have had trouble
with keeping the G8018's operating. I occasionally trip the breakers on
startup. I am thinking bad filter Caps. Perhaps someone could give some
opinions on this (Crazy) idea.

Just booted it up and it runs wonderfully :)
So, the IOP firmware for the E series has not only been found, but confirmed
to work! It was so neat to type "HEL-A000..." on a terminal this morning.
The dual E's are noticeably faster than my dual 2100 Access system, but not
as much faster as I would have expected. Odd, since the processors are
significantly faster, and using the high performance memory option.
The basement doesn't heat up quite as much running on two E's as opposed to
two 2100A/S. Also, I seem to be able to run it indefinitely without tripping
a circuit breaker. Nifty! I ran in to lots of cpu problems this morning, and
had to go through every one of my 21MX-E spare cpu's to get a working
combination. Yikes - makes me wish I hadn't given away all my E's.
At some point in the future I should probably try the M series firmware
board, just to be sure that works as well.
I also wound up having to scavenge some parts from my 2100 Access system to
get the MXE Access system up. Bummer! Hopefully some trades will produce the
necessary stuff to have both operational. Yup, I'm pondering some RJE setup
between the two :) Oh, except I apparently only have one set of processor
interconnect cables, thought I had two :\ Making up THOSE cables will suck.
Anyways... just wanted to let folks know that the E series IOP firmware is
definitely a go. The biggest problem I had was trying to figure out how to
set up the FAB board. I'd really have preferred to go the FEM route, but
Access is so hard-coded in the system processor side of things.

Jay West

That's what Cadmus (German CAD systems producer) did with their 680x0
boards; they fit in a normal QBus chassis, use standard QBus
peripherals, and run UNIX. I've never owed one, but I've (briefly)
used them.

Got a call from my High School, they had found more "old computer junk" in a
little used closet under a stairwell. They said "come get it out", so I did,
and I was pleasantly suprised. Here's what I found...
Four, yep... FOUR of the rare HP 12920 MUX panels.. at least two of which
have full cable sets!! These aren't the mux controller cards, this is the
large metal bracket (which has it's own circuit board) that the 12920 mux
set connects to. And the cables for these are a bi***, double hooded affairs
on one end, centronics style connectors on the other, a three cable bundle.
Anyways, this totally makes my day :) I will keep one or two, the rest are
available for trade.
A CDC 9715 "front panel filler kit". The CDC drive (a single one anyway)
took 1/2 a 19" rack space horizontally. So this kit includes the extra
filler panel to bring it across the 19" span. Also included are a full set
of unit select plugs (look like they'd work on an RL02?).
An Emulex SC02/SC11 disc controller. This looks to be Qbus. Dang. I have
qbus systems I'd use it on, but I'd rather have a unibus controller ;) The
board comes with some interesting things in the box. Full technical manual
on the board, plus a handfull of color brochures and specification sheets
(marketing glossy's) for all the different products that Emulex made in the
way of disk controllers and such. Then there is an envelope with a large
amount of the full line of emulex products glossy brochures/datasheets as
well.
An odd HP "power controller". I've never seen anything quite like this. The
power controller is HP part 30311-60001. It has a lot of the standard HP
power connectors (yeeehar! Battery eliminator plugs!!), and test points on
the front for "battery test". Then there's a large bundle of power cables
that goes to a rackmount panel with separate switches for "lower memory" and
upper memory" standby and run with lights for DC status, battery status,
etc. This sure seems like it would be some kind of power management for the
21MX M-series, but I've seen the battery backup option for the M series and
this wasn't it. Odd.
A partially canibalized HP 2112A power supply
A CDC PA5A1 & PA5A2 hardware maintenance manual. The pictures look very much
like the CDC 9715.
Misc. parts from an 11/03 or maybe 11/23 front panel (the 3 white toggle
switches assembly) - bezel & circuit board
This appears to be a 3rd party manual for DEC memory - "CMV-1000 MOS Memory
Manual"
Then there's some manuals for various 9" monitors frequently used with old
systems - sanyo, ball (a TD12/15 service manual), ikegami or something like
that...
I left a bunch of cannibalized 21MX power supply stuff behind, as well as
some power supply parts for a 7970 tape drive. I will be going back to get
those... as well as a pristine, apparently never installed brand new
old-style HP 19" rack. Now I have a place to mount my other 7970E and 7906
and 7900A :)
Lastly, some really odd stuff I left behind but will go back to get. I have
no clue what this stuff is... honestly, it looks like stuff from an old
Frankenstien laboratory in the movies. Desktop metal boxes in this mottled
black paint, with HUGE brownish/redish dials on them that appear to be some
type ceramic. Large analog meters on most of it. No brand name that I could
see but it really didn't look "home brew". I could tell is was FAR older
than the HP stuff I was looking for. Maybe when I get that stuff I can post
a few pics and people could try to guess what it is. It's very clearly not
computer related though - believe I saw a few tubes in some of them.
Oh, I also got a voice coil with 5 heads attached to it. It's quite odd
looking - the heads don't line up. There's maybe two heads on the bottom of
the coil that are aligned "over under". Then there's a third one off to the
side. Then a glass reticule, then two heads above that that didn't line up.
Wierd. It looks like something that came off a borg arm ;)
