Since I have some cables for one, I thought I'd go digging. These

I was curious about that... specifically, I caught that there's a
DHU/DHV-compatibility setting, but I was curious how far back there's
support for this board. I'm sure it'll work with modernish versions
of VMS, but what about PDP-11 operating systems? (most specifically,
I'd be thinking of RSTS and 2BSD). Anyone have any experience with
that? (My own is with older products on older machines, but except
for DZ11s and DLJ11Js, I think some of the older multi-serial
interfaces are less easy to find these days).
