I had cause over the weekend to take apart my 8E dual-bay system (the
TU10/TM11 is being traded off). I remembered there was some discussion a few
weeks ago about the mid-sized dec cabinets with the sloped top front, so
figured I'd post a pic. Mine may be somewhat unusual in that the operator
controls for the TU10 are on this sloped front at the top rather than the
bottom left quadrant of the drive. The rack next to it with the 8E and TU56
has just a blank sloped front in that "PDP 8E Yellow".

Was there a conclusion to the modelnumber of the rack itself. The tall
ones are H960. Are the shorter ones H965 ?

Some confusion I guess.
Looking here (document pages 8-5 and 8-6, which is file pages 380-381):
http://bitsavers.trailing-edge.com/pdf/dec/pdp8/handbooks/Small_Computer_Han
dbook_1973.pdf
It lists the standard H960, and an optional shorter cabinet as the "H967".
However... I am not sure that the cabinet pictured as the H967 is what I
have (in the picture link below). What I have - there is that sloped top
front, AND it seems a fan was intended (and is) mounted to the bottom of the
back door. The H967 pictures in the manual above show no sloped top front,
and a big fan assembly on the floor of the rack.
But... in that same SCH'73 manual, it DOES show the rack I have in various
pictures (with no mention).
I have never heard/seen mention of a H965. Perhaps that's what I have. Or
perhaps the H967 is what I have, and there were just options to order with
or without sloped front plate or fan assembly? Also interesting, the cable
trays that fit in the cutout in the bottom of the rack - in mine they are
mesh. In the H960's I have seen, they were all solid sheet metal. Perhaps
that floor mounted fan was an option my racks didn't get... Dunno....

Hi Jay,
It's a H967. Dec did publish a cabinet and accessories catalog, but I don't
have one handy. It might be in various site prep guideline books also.
Maybe on bitsavers?
Thanks, Paul

Here's a page I've just scanned from a 1978 DEC sales catalog showing
the H960, H967 etc.:

Steven... thanks a ton! I think you've solved the mystery.
What was in the documents you scanned is clearly my rack... so it's definitely an
H967.
But if you look at the handbook link I posted earlier, it ALSO lists an H967, which is
clearly different than mine and the document you scanned (ie. Fan sits in center of
cabinet pointed downward with a cowling, and the top of the rack is flat, not sloped).
So it would appear that over time there were two very similar, but different racks - both
designated H967.
Thanks!

No worries Jay, I think you're right about the H967 variations between the handbook
and the sales catalog. Back then
they didn't put 'Subject to change without notice' on everything, it was a
rapidly evolving industry and I guess
that sort of thing was just expected.
By the way the 1978 DEC Sales Catalog I scanned is a fabulous item, I snagged it off eBay
last year. If I had been
stranded on a desert island and needed to mail order DEC gear back then, this is the doc I
would want.
I'm slowly scanning the whole catalog (each page at 600 dpi) which I will turn into a
PDF for everyone to have. I've
been at it for a while and I'm about halfway through.

The H950 was the rack only. If you add a few options, doors, sides, fans,
etc, Then it became the H960 cabinet.
The H967 is all 90 degree angles on the top front. the bezel is angled, and
came in several varieties, with or without switches, color, etc. There are
2 screws on each end of it that hold it in place. As I remember they are a
pain in the rear to get to.

I'm not sure where I got it from. Now I'm not so sure I've seen it
anywhere.
Oh well, It would be nice to know what to call the different DEC racks.
There are so many in different shapes and sizes.
