It looks like a version of RSTS/E to me (but that's mainly because I
know it isn't RT-11 or RSX-11...)

It's almost certainly a QIC-02 controller, probably doing TS11 emulation.
The sure way to test if its doing TS11 emulation or not is to drop into
console ODT and see if there's something living at the TS11 CSRs at
17772520.

These control the 3-wire DEC power controller bus.

Warren may want to correct me if I'm wrong, but aren't non-Unix issues
like these best taken to forums such as vmsnet.pdp-11 and comp.os.rsts ?
