I'm even more curious what a PDT-11 optimization is doing in an RSX
driver...was there at one time an RSX product product planned for the PDT
family?

I've never met a PDT-11/110 in person.   The docs say they were
downline-load-only -- so what DID they run?   MRRT11?   RSX11S would
certainly make sense.   Also, DEC dumped a lot of the PDTs to their
own employees, so maybe someone made a few tweaks to the RSX code
for their own evil purposes at home.

I'd suspect 11S should work right out of the box. But both the /110 and /130 was Qbus, so I'd suspect them to be pretty straight forward. The one I was thinking of was the /150, which is the one I assumed you were talking about when you talked about the serial chip and DUV-11 emulation, John...
