Was this the precursor to the NBI 68010 QBUS Unix system (I forget
the marketing model name or number).

I owned on of those at home back in the day[1], complete with
10 Mb/s ethernet board and a DH-11.  It ran an off-the-tape
compilation of 4.2 BSD, and it was absolutely covinced it was
a VAX :-)

I was running a small usenet hub on it, and when I connected the
Telebit, the machine started to panic in the DH11 driver under 9600+
baud serial load when there was also any ethernet traffic present.
I called a friend and said "please send me dh11.c and .h from the
4.2 release tape."  Compiling them required changing a single #define
(compile for QBUS, not UNIBUS).  I re-linked the kernel, rebooted,
and the problem vanished!

Oh how I miss that machine.  It was like I had a VAX in the 2nd
bedroom, but with a proper CPU :-)
