Thanks to the recent adoption of yet-another-DEC-halfrack, a DEC SA600
rack needs to go. Here are some pics:

The cable frame and the SDI cables on it are no longer here.
It's a bit of an odd rack, having held the massive RA90 hard drives in
its previous life. I believe once those brackets are removed, normal
rack holes remain, but I can't be certain. As seen in the pics, I
cleaned it of most of its rust and it looks pretty good. Purists will
want to repaint it.
Local pickup only in the NW Chicago suburbs. It's about 5' high and
weighs a lot more than it looks like it should. Be prepared for a
battle getting it up the stairs.

Yes, they are normal rack holes. I keep an RL02 drive in mine (and a
microvax 3800, but with a rather improvised wooden mount :)
It's not _that_ heavy and few U smaller than an H960

An empty H960 is still pretty heavy, but I did manage to get one up
the stairs solo once. Won't be doing that again. :-)
If I needed a rack, it looks like a nice one for a
non-workshop/non-datacenter installation. I had to wedge that same
H-960 into a commercial basement in a 1900s storefront (my mother
rented the main floor for her typing business) and between the slope
of the floor and the low ceiling, it was difficult to place the H-960.
I, however, am not looking for a rack and don't know anyone else right
now who is looking. For my own stuff, I'm in the middle of cleaning
and loading one of the table-top sized DEC racks that used to contain
a PDP-11/03 and RX01. It's about 12U (twice as tall as an RX01) and
has a Formica/particleboard top. Makes a nice coffee table.

Sounds neat, I'd like to see a picture of that, unless its to much of a
hassle.

Just refreshed my own memory - it was sold as a "PDP11V03". Having
problems finding the DEC "H" number for the enclosure. It's been
discussed on this list before, but I don't remember the exact part
number.

I have a H960 in my
flat, 2nd flor. When I got it, I removed the
riverts. (There are 28 of them.) So the top and the four side posts
came loose. The side panels and the back cover are removable anyway.
So I put everything upstairs in parts. Then I used ordinary M6 screws
and nuts in place of the riverts to put the thing together again.
Simple and works well.
I did the same when I got my "low boy" DEC rack...

nearly as heavy as me by myself without straps/ramps/wheels/mechanical

Is there clearance between the side of the H960 and the grey sides for
the M6 bolt heads, or does your rack lack the hang-on metal sides?

ObRackMisadventure...
In 1994 I became the proud owner of a VAX 8250. (I even got to remove it
form the machine room at Mannesmann Tally in Kent)
One of the three racks held a TU81+ tape drive and nothing else. Since my
friend and I were breaking the machine down and moving it to the upstairs
of my house, we removed the tape drive from the top of the cabinet and
proceeded to nearly kill ourselves squeezing this huge cabinet up a tiny,
residential staircase. Only after getting to the top of the stairs do we
discover the two 50+ lb steel balance plates that are bolted to the
insides of the frame. *facepalm*
The other two racks were shoved straight up the staircase after taping a
section of carpet to the top corner of the cabinet to act as a
"gliding surface". My back still twinges thinking about that day. The
four RA-81 drives were no picnic either. :)

Well. Remove everything that you can remove easyly so that
only the
four posts, bottom and top are left over. Lay the rack on its left or
right side. Step _into_ the rack so that you look at the bottom. Pick
it up, so that the posts stay horizontal. You have to try a bit to find
the right position to grab to have the whole thing in balance. Now
walk. Surprisingly easy. I even got a rack upstairs that way.

There is plenty
of space. The rivertrs aren't that small too.
Ohhh, sorry. I just noticed that my racks are not H960. They look much
more than the aforementioned SA600 rack. That confused me. So they may
be of the H9612 / H9613 variety. Actually the H960 is welded. My
PDP-11/34A came in a H960. I had to leave the rack behind as I could
not dismount it. It didn't fit my car... :-(

I chuckled when I read that H960s are hard to move...I've moved lots
of them exactly this way. It really is the best way to do it if you
can't just roll it somewhere. They've gotta be the lightest racks
(empty) in the industry.

I've moved hundreds of H960's and learned a lot of tricks- mostly
good. I could 2 on the floor of my van and a 3ed on top.
Anybody else on here ever move an 11/70 in a corporate cab down
several flights of stairs in a commercial building? Remember, they
don't come apart- CPU, memory, expansion all in one.

holy... I've moved one.. but never down a flight of stairs, where there
casualties?
Although, we are all amateurs compared to the fellas with CNC machinery
in their garage. Admittedly no-one probably ever moved a CNC mill up a
flight of residential stairs...

Those guys know the tools of their craft every bit as well as we know

Ah, yes! It's also known as a J-Bar (I guess because it looks like a capitol J). I
have one. It's amazingly useful in moving loaded racks when you have a *small* ledge
or gap to get over. Mine is more like a 6' pry bar with wheels at the leverage point.
The "blade" is ~6" wide and 4" deep (just right to get under racks
and such). It has a 6' wooden handle (again about 6" wide at the bottom and
tapers to ~4" and is 2" thick). The "wheels" are 6" heavy duty
solid wheels. I think I paid ~$100 for it new. It's seen a lot of use! Worth every
$0.01 I paid. Friends who've helped me move equipment (mine and theirs) love it too
(it's probably my most borrowed tool).
Basically you put the blade under what you're trying to move and "lever" it
up so that some of the weight is on the wheels of the J-Bar. Because the J-Bar's
wheels are much larger (and probably in much better shape than some of the casters on the
racks) it makes rolling the rack over "rough" terrain much easier. Usually I
use it when I'm moving stuff into/out of a lift gate truck. There are
"gaps" to get over that usually results in a lot of straining without the
J-Bar.

Well. Would have been interresting
to tow a H960 at 20km/h over a
distance of more then 100 km on the german Autobahn... ;-)
The next problem was: There is simply no space left in my flat. It's
getting a real problem. :-(
