I had a nice talk with an old friend earlier today, and we talked about how
some companies were so proud of their products that they never put their
name on it. Sometimes a logo, sometimes only a part number.
Bitsaver is great- I don't don't know what any of us would do without it.
But There are a lot of items that, at least I, can't turn up there or on
Google.
While looking for the ABLE (ACT) board that Mattis was talking about (and I
found it for a list member who has first dibs on it) I came across:
Computer Consoles 343d01533
Computer interface Tech -looks like a DZ11 clone
CMD CDU-700/T witch I think can be upgraded to a M/T SCSI Unibus
Simpact Assoc inc ICP-1600
DPD might have been bought out by CDA Computer design and
Applicationd.which might be a subsidiary of Analogic.
MM3000,
40199 2mg,
FPPC
Some of these I've heard of, some not.
I have a few hundred DEC compatibles, and I'm tired of going through them.
Duel, quad, hex, and 780. A lot of Emulex, dilog, ADAC, Data Translations.
Please contact me off list if you are interested in any. Pics would be
nice.
Thanks, Paul

And long after WWII! In the 1960s, I had a Motorola 140D (140
for the power, "D" standing for Dynamoter) mobile radio (6 meter
ham band) in my car. Everytime I keyed the mike, the dynamoter
would instantly spin up with a loud whine. Such radios were
normally housed in the trunk of the car and required heavy wire
to carry the 12 volt battery current for the dynamoter.
My Monarch 10EE lathe originally came with a big motor-generator
to power the variable-speed DC motor. Later versions use
thyratrons, while even later ones were solid state, but they all
continued to use DC motors. The variable-speed DC drive was
very similar (identical?) to elevator drives, known as the
Ward-Leonard system.
To bring this back to the RK05, someone asked if anyone had a
copy of the RK05 IPB. If you still need it, let me know and
I'll dig it out. I haven't packed it for my move yet, but
the drives are.

They have a min $10 order on _every_ part, and also a min of $25 on the total
order.

Yeah, those are the ones.
Note that ConnectorPeople has a relatively large minimum order. Quest has the
male connectors (i.e. female pins), but not the females.

According to one dealer Web-site, what I think are those connector shells are
now out of production.
However, as I indicated, I have located several places that still have some,
and I have ordered some to verify that they are the right thing. If they are
(they should be here at the end of the week), I will send another message with
part numbers, sources, etc.

I believe Chuck is looking for the other way SD to micros i.e. a size reducer.

hi
any chance someone has worked with the Motorola IDP m68EC0x0 board and
has the manual of the 68EC020IDP CPU module?
let me know
p.s.
have you ever seen the IDP-net card? any information on the IDP bus
timing? (i'd like to develop my own net-card for the IDP bus, but I
need the timing spec)
So, it turns out the power connectors (plastic female shell with metal male
pins, etc) widely used in UNIBUS PDP-11's (e.g. to provide power to
backplanes, etc) are still available, if anyone else wants any. (No doubt some
of you already knew this; this is for those, like me, who didn't! :-)
The 3-pin ones are used for the remote power on/off cables (used extensively
in DEC gear, not just UNIBUS PDP-11's).
They are 'Commercial Mate-n-Lok', now made by TE Connectivity, who bought AMP.
Here are the current part numbers:
1-480305-0 3-pin female shell
1-480276-0 6-pin female shell
1-480277-0 9-pin female shell
1-480324-0 15-pin female shell
60620-1 14-20AWG male pin
The 6- and 15-pin are for the backplane power connecters; the 9-pin were used
to power backplanes in older machines (e.g. PDP-11/10). There's also a pin for
smaller gauge wires, e.g. for the power control cables, but I don't have the
number right here.
I have checked, and these do plug into old DEC gear properly.
I got mine from Digikey; their page for the line is here:
https://www.digikey.com/products/en?FV=ffec0ef5
Go to the bottom, where it says 'Housings', and click on that, and they will
all show up. (There are cross-links to the pins when you click on a particular
shell.)
Noel
PS: I'm also tracking down the 8-pin connectors used in the H744/H745/etc
regulator 'bricks'; an update on them in a day or so.
