I found an H720F power supply. Anybody knows where it is used for?
I't a self containing unit, it's not using the bricks and it does
not ring a bell for me.

If I'm reading correctly, it seems to be the PSU for a 11/15 and/or
11/20 according to 1120_SystemManual.pdf.

I think it was mounted on the inner back door of the H960 and used for
TU56's, TU10's, etc, The "E" might be 120V, and "F" European.

I have one to power my RK11-C contorller. I can't rememeber if the unit
for my DX11 is the same supply, but it might well be.
I think it was often used with backplanes of flip=chip cards.
There's a similar-looking unit, the H734, IIRC, that probvides the
votlages for the RK02/RK03 (Diablo Model 30) drives. DEC didn't use the
normal Diablo PSU appareently.

points. This PSU has a flat plug, identical to the
ones on the bricks
like the H744/H745. And it's different than the one in my DX11, that one
I seem to remember my H720 is mounted on a 10.5" rack panel and has a
barrer strip wired ot a mate-n-lock plug to git that 8 pin output socket.
I think one of my DX11s has an H720F PSU, the other has some other unit,
but I would have to dig them out...

Sorry, I probably meant the TC08 and TC11. It was used in a number of
products. The H721 was common also.

Hmm, I tought the PSU for a TU-55/6 used these small colored connecting
points. This PSU has a flat plug, identical to the ones on the bricks
like the H744/H745. And it's different than the one in my DX11, that one
is more 'flat'.

Subject: Re: H720F psu
Good Morning, Gentlemen:
I have obtained a subscription to the Classic Computers
discussion round-tabe about a week ago and 'listened' in,
in order to get an idea of how things work, before I stick
my head into it.
My interest kind-of centers on Kaypro and I had hoped, to
find some participants with whom I could chew the rag on
that topic. - Perhaps I will.
My current post is prompted by lots of notes on DEC and
their power supplies. I have an H771-A, to which anyone
is most welcome, who wants to pay the postage.
Beside it, there is also a set of guts, without chassis:
The board with heat sink and diodes etc.,
CV-transformer (Acme Electric, T-4-71354) with capacitor,
two electrolytics (14,000 & 18,000 uF) and EMI filter.
Ehhhh, just took another look, to see if that chassis is
lying around in some corner. Negative. But I found another
thing with a "digital" label on it: P/N G8018, called
"Regulator Board". And four 8" drives: Qty.2 "digital"
P.N. 70-13077-00 Rev L, Serial # WB268953-221 and
WB270772-222 and Qty.2 "Shugart" Model 800-8 (my guess),
Serial # B02488 and H32847. And two boards, which are
probably controllers, are 8 x 15.75" and contain circuitry
for steppers, photo sensors (index hole) and solenoids.
one is marked "94VO digital TF-1".
The stuff sits in Ontario, 30 miles East of Detroit, MI.
If there is any interest, I'll send pictures. For direct
contact: 519 798 5717.
Friendly Greetings, Armin.
