IIRC, it's actaully a PDP-11 and the OS is a munged
version of RT-11.
The filesystem it uses on TU58's is the same as RT-11's filesystem.
That doesn't mean it's running RT-11 :-). A VAX-11/780
has an LSI-11 as the console processor, it uses the RT-11 filesystem
on the boot floppies, and that doesn't mean it's running RT-11 :-).
On the other hand, VAX 8600 series CPU's use a PRO 380 console
running an operating system that *is* derived from RT-11. (The
VENUS conditionals still abound in the RT-11 sources, even
though AFAIK a build hasn't been done in over a decade.)

Some of the later 8000 series used Pro380's, I was told.
The 8600s had an 11/0x (for some value of x, probably 4) which lived in the
same Unibus box as the VAX Unibus peripherals. Nautilus class machines
85xx, 8700 and 8800 had Pro consoles 350s and 380s. The later model 88xx
systems used MicroVAX-IIs as a console. I no longer have any 8xxx class
machines, but I still have all the consoles (they are _much_ easier to
store :-))
I had this theory that Digital used excess systems as consoles and as they
ran out of a particular type, created a new system to use the next set of
redundant hardware...

The 11/780 used an 11/03. I think the 8600 used a T-11 with a somewhat
strange memory management setup which wasn't part of normal T-11s.
