Maybe someone has a spare pair of mounting rails for a DEC RK05 drive, so
that I can finally mount it into my H950 rack?
Offers from all over the world accepted :) (I'm located in
Austria/Europe)

Klaus,
never seen a RK05 in the wild, but what are the HUGE differences to
the moderner Rack-Reels. I could supply this ones (HP or IBM, you
choose). Even a small workshop is available here if mechanical
corrections are to be made.
If you could provide a picture, I could search my project-boxes if I
find something suitable which could serve your needs until you find
the original ones.
Regards,
Wolfgang
PS: I'm in Austria too. Located in Linz. There's Gerhard from
http://www.compuseum.at/ reading here too. He has also a nice
collection of '11 and '8 stuff.

Chassis-Trak still exists.

If you have to ask this question, then you clearly haven't seen old DEC
equipment ;-)

Hehe. I've seen that kind of equipment quite a few times. But the RackRails
were never that interesting ;)
Just tried to help out with items in stock.

BTW: What Rails do I need for a 11/23+ CPU Box?

Assuming it's a BA11 (which I think was the original CPU box for the 11/23, but I
could be mistaken), it's probably in the manual for the case. The rails come in
several parts (with brackets, etc), which the scrappers seem to sell almost universally
for about $30 (US) each.
The BA23 (which I'm on the lookout for, if anyone has a spare; also looking for BA123)
is in a similar boat. I don't think any /23 or /23+s came in a BA23, though.

They did; a lab I worked in many years ago had a direct-from-DEC 11/23 in a BA23
chassis. It was rackmounted with an expansion chassis, running RSX.

The PDP-11/23 and 11/23+ came in a BA11N or BA11S, and those don't have
conventional rails. Instead they have a wrap-around black steel cover
which is bolted into the rack. It covers the top and the sides, with
two front flanges that bolt to the front uprights of the rack, and
adjustable panels at the rear of the sides which bolt to the rear
uprights. The sides each have a small lip bent under the body which
the BA11N/S box slides onto. From the front it looks a bit like this
(if you have a fixed-width font!):

...and I'm looking for one or two sets of the rear flanges, if anyone has spares.

The biggest obvious difference is just the boot ROMs, 2K x 8 in the
PDP-11/23 and 23+ but 8K x 8 in the microPDP-11/23plus, with additional

of course, but the CPU is essentially the same.

I just made some out of sheet metal.
