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.)
