I assume the dweeb in the picture is not included. I doubt you'd want him
anyway...he looks like trouble.
So, Geoff thinks this is an 11/33. I've never even heard of an 11/33.
But there you have it. I've done my part.

Me neither.
The boards shown in the photo don't appear to be DEC boards. DEC
boards have color coded handles along the front edge of the board and
no ejectors, or they have a die-cast frame with metal ejectors. But a
board with plastic ejectors and nothing else along the front edge
doesn't match DEC practice that I have ever seen.

Looks like a Micro PDP-11/53 to me.

It's a pretty safe bet that it's a Micro PDP-11/53 <URL:

There is a PDP-11/53 badge on one of the other pictures, as well as a
MicroVAX II Badge. It looks like there is a good chance that both
are in there.
It would really help to have better pictures of what exactly is being
offered. The one cabinet that is open on the ebay webpage looks like
it probably has some custom boards for the CNC machines.
Probably worth the price if you're local, and have a way of moving them.

It's an 11/53. That's the low end of the J11-based Qbus PDP-11 product
line. Though it's still significantly faster than an 11/23 (F11 chipset).
The J11 chip has capabilities roughly comparable to a PDP-11/70, the
biggest and most powerful TTL-based PDP-11 CPU that shipped as a product.
The J11 has microcoded floating point, but can optionally use a separate
floating point coprocessor chip; I'm not sure whether the 11/53 can
accomodate that chip.
Qbus J11 systems included the 11/53, 11/73, 11/83, and 11/93. The
main differences are the cache size (or absence), the clock frequency,
support for the floating-point coprocessor chip, and the amount of
main memory present on the CPU board (none for the 11/73 and 11/83).
The J11 was also used in the 11/84 and 11/94 Unibus systems, which are
the Unibs equivalents of the 11/83 and 11/93.
The J11 was used in the Pro 380 personal computer, and was used as an
embedded processor in many DEC devices, including the HSC60, HSC90, and
HSC95 storage controllers.

The J11 was also used in most UK traffic light control systems, so I've been
told....
Oh, apparently the Thames Barrage (massive flood control device on the River
Thames in London) is controlled by a VAX 3100 - the company I work for used
to maintain it :)
