Heh.  This thread got me looking at a piece of software I wrote a long
time ago -- a utility to help you configure the components of a Q-bus or
UNIBUS system with the correct CSRs and interrupt vectors for DEC
operating systems to recognize them during autoconfiguration.  It's in
the archive, and called sysgen, because it's a clone of the relevant

Anyway, it turns out my tool has had a bug in it since 2004, that kept
it from working correctly with boards that need specific CSR settings,
but have their interrupt vectors in floating space -- like the DC11,
which is why I noticed the problem now.

The corrected version is at https://www.hamartun.priv.no/tih/sysgen.tar.Z

I'll ask Warren to replace the one in the archive.

Most people who graduate with CS degrees don't understand the significance
of Lisp.  Lisp is the most important idea in computer science.  --Alan Kay
