I'm just curious; I picked up a PDP 11/05 last weekend, but instead of the
processor cards laying on their sides, these were standing up. This resulted in
a configuration with two other plastic covers (one about 1" high below the
standard 11/05 front panel, and the other about 7" above the front panel.) Is
this a standard or optional chassis for the 11/05? I also picked up the dual
cassette drive (no cassettes or software yet though), so it looks like a nice
little system.

The 11/05 and 11/10 came in at least 3 different boxes and at least 4
different backplanes. If you have specific questions, reply or send me your
phone # and a good time to call.
Thanks, Paul Anderson

Sounds like you are describing the 11/05 10" system unit.
It's a standard chassis. 11/05S IIRC
It has a 1 rack unit panel below the front panel.
And a 3 rack unit panel above the front panel.
It has the power supplies along the right side (if you're facing the front
panel)
A 9 slot backplane and room for 2 or 3 additional 4 slot backplanes.
sound right?
The docs for it are on bitsavers

I was under the impression that 11/05S refered to the later version of
the CPU board set (which could end up in any mounting box). The main
differences to the user being a couple of jumpers, one to disable the
console port (allowing you to use a normal DL11 card for this), the other
to diaable the bus arbitration, allowing the machine to be a slave
processor on the Unibus of another machine (!)

Odd. The 5.25" box is like that, but the 10.5" one I saw had the PSUs
across the back. It was the same box (BA11-K) as is normally used for the
11/34

I'm willing to accept more than one version of the 10.5" chassis...
My 11/05 has the same power regulator as used in the 5' chassis
along the right side and has a H744 behind that.
I seem to recall seeing an 11/05 with h744s along the back as you describe.

There was a standard configuration for the 11/05 in the BA11-K 10.5" high
mounting box. It sounds like this is what you have. The main differences
are a totally different backplane, more space for expanison (obviously),
a different PSU obviously) and that the console terminal cable plugs into
a little dual-height board that plugs into the CPU backplane.
