Hi guys,
I have to make a console cable for the VAX4000/300 and an VT420 Terminal.
How are the pins to be connected? One to One or with an rollover
(1-6,2-5,4-3)?
Regards,
Holm

Rescued a keyboard from the dump earlier which is about the same style/size
as an IBM model F, only a darker grey color (and not a buckling spring mech).
Layout-wise, there are no F-keys at all, but keys on the numeric keypad are
labeled things such as 'pan', 'curs', 'local', 'dejag', 'vern', and then
there are eight status LEDs above the keyboard area (on-line, local,
interp, busy, pan, cursor, dejag, 2nd).
Does this critter sound familiar to anyone? I didn't see anything at the
dump that it obviously belonged with, but I may return tomorrow and
double-check, and knowing what I was looking for might be helpful. Of
course it's possible that whatever it hooked up to is long-gone, or even
had already been hauled off from the drop-off area for processing.
cheers

About the DEC cards: the M8043 is a DLV11-J (a four-port serial card), and
the M8059 is an MSV11-L (up to 256KB memory card - but I'm trying to get that
one).

As far as I understand it, pretty much all MMJ sockets are wired the same
and the crossover between transmit and receive normally happens in the cable
so you need the rollover.
Even if this is not true in 100% of cases, it does appear to be true at least
in the case of connecting terminals to hosts.

I have a sizable collection of HP-1000 circuit cards, as well as a couple of PDP cards.
They take up a lot of space in my workshop, so I'd like to find a home for them.

Re: RT11 / RSTS-E games
I obviously have done something wrong when moving files about etc. Hence
depending on which way you get there, they may not link.
For now all the games I have are available here:

I have a Xerox 820-II with CP/M 2.2, monitor, dual disk drive, keyboard, daisy wheel printer, manuals, and cables. Wondering if anyone is interested in saving it from the dump, OBO. Bad news, I powered it up recently and the screen flickered and jumped for about 5 minutes before the wisp of smoke. The visible damage is a film capacitor on what looks like a power supply board in the monitor. Five years ago it powered up and was working as far as I could tell. Baltimore, Maryland area (USA). Not a list subscriber, will check list daily for a while, then weekly...

Anyone have any literature on the Vermont Research 5017?
It was a cartridge drive shipped from 1975 until 1985 probably rebadged and
sold under some system manufacturer's label. Most likely the first HDD to
use embedded servo in a production drive.

I just posted the winners for the Type ?n Run contest for April on RetroBattlestations. Lots of very interesting programs that people submitted. Entries came in for a variety of computers like the IBM PC, the BBC Micro, the TRS-80 CoCo, and even one for the Texas Instruments CC-40!
Check out all the entries, and maybe submit a program of your own! The Type ?n Run contest is an ongoing challenge with winners selected every month.

Does that mean there was an ASCII version of the 029, or that there was
something in the card reader software on TOPS-20 that converted EBCDIC to

Just another video showing one of my units for anyone who might be
interested.
I was lucky to get this one in such a clean undamaged condition. It did
require some work to get it into shape for this video though. Bad solder
joints on the analogue board...it's almost a standard feature of these
machines, just like leaky caps in the later models!
Anyway...

These were great tape drives. The 604 was 75ips versus 150ips for the 607. Both drives were 200/556/800 bpi 7 track units.
The weight was a killer. But they were extremely reliable, easy to work on and easy to interface. Al has manuals on them (I know because I loaned them to him) and I have a lot spare parts if someone wanted to try to get them working.
These would be a good choice for recovering old 7 track tapes. They used vacuum tensioning columns and vacuum capstans. So very little contact with the magnetic slurry side of the tape.

Why is that, can I ask? I mean, it's not like a thief's going to come in and
steal the thing (which is indeed the reason why collectors in other areas are
often secretive) - it would take a truck and a crane, for most models!

Cool story; thanks for the link - but the page says it was a 360/30. (The
smallest 'real' 360 - the 360/20 was a lobotomized 'sorta' 360/.)

CHM was able to obtain volumes 18-20 of the IBM 2050 drawings, which are
the microcode charts and ROS dump. I got them scanned and uploaded yesterday
to http://bitsavers.org/pdf/ibm/360/fe/2050
This was one of the things that I had been trying to locate for a while now.
PDP11GUI is at v1.46 now.
Among others I fixed an annoying bug, which prevented proper terminal
output when running certain diagnostic paper tapes:
Filling <NUL> chars were sometimes interpreted as backspace!

9; yes; it has the standard 9-pin connector as used on the 11/05-10, and the
early /40s and /45s. (FWLIW, the documentation for the PM-F11 says that _it_
comes with either the same 9-pin connector power harness, or the harness with
the newer 15-/6-pin connector pair, and gives part numbers for each.)
The harness of this one is subtly different, though - instead of all fast-on
tabs at the backplane end, there is a DuPont header on the backplane (looks
like 10 pin), and a bunch of the pins on the large 9-pin connector are
connected to that (not just ACLO and DCLO, but e.g. there are a pair which
are connected to +5V, and another pair to ground (the latter two also go to
fast-on tabs).

Oh, I'm sure it's _some_ form of SPC backplane - it has the NPG jumpers from
CA1 to CB1 on all 9 slots, for instance. And it has a bunch of wires running
>from 1A/B down to the CDEF part, and then back from CDEF to 9A/B. And the NPG
is routed from 1A down to CA1/CA2, and then back up to 9A.
But I'm trying to figure out exactly what sort of SPC backplane it is. E.g.
it looks like slots 2-8 _might_ be MUD (the signals from 1A/B are bussed
across all those slots on A/B, over to 9A/B). But without documentation, or
a lot of ohm-meter work...

Hi, all, I have a Plessey PM-D11/SPC-1 backplane here, and I'm interested in
finding some documentation for it. I looked online, but couldn't find
anything?
This site:
http://www.compsy.de/gebr-vax/repman_verl.htm
seems to list one, and does apparently 'rent' documentation, but I'm not sure
they're ready to rent something to someone on another continent. (If someone
in Europe can assist in dealing with them, I'd be extremely grateful.)
I do have a manual for the vaguely similar PM-F11/SPC backplane (which I would
be happy to scan promptly if anyone has a need for it; otherwise, it will get
scanned when I obtain a round tuit), and that, plus an ohmmeter, would
probably allow me to eventually figure out the PM-D11, but I figured I'd look
and see if I could save all that work, and put it into something else... :-)

I can't seem to find the definitive catalog, but I know there were
folio packaging of several of the titles available for sale. I saw
Starcross hanging on the wall at the Digital Store in Columbus, OH
(back when there _was_ a brick-and-mortar store), and I am reasonable
certain there were others, definitely more than just the V1 Zork.

Ooh... that's right... there's an implentation of Star Trek on the
Z-machine. I'll have to go grab that to see which version it's based
on. Personally, I'm used to the one that was in Dave Ahl's "101
Computer Games", the one that has the short range scan that represents
each item with up to three chars and empty locations with all spaces
(as opposed to a simple grid with 1 char per filled spot and, ISTR, a
'.' for empty locations).
When I get the opportunity (later this weekend I think) I will check
my backups for the RSTS/E mod I was mentioning. If the RT-11 ZEMU
doesn't compile on RSTS/E as is, it should be a 1-line mod.

Anyone got any RT11/RSTS-E games? I'm back on with my project to recreate
the PDP-11 that I goofed around with when I was a kid. (Its accessible via
the bbs... bbs.cortex-media.info 4223)
I have 2.52 version of Dungeon, and a version of Star Trek. Anyone got
anything else?
I'm still looking for Oregon Software Pascal as well...
Thanks!

Had to Google 'imaginary power'... Not a lot of experience with high-power AC
stuff! :-) ('Imaginary power' is probably not the best term to use, because
there are actual currents involved; I like the 'reactive power' name better.)
The article I read said that in reactive load which is high in inductance
(which is, I assume, the source of the high reactive load in rotary
convertors - or am I confused - a common happening, I concede :-), judicious
application of capacitance can reduce the reactive load. Why isn't this used
with rotary convertors to reduce their reactive load?
Any idea what the active and reactive powers/currents were in that attempted
installation?
