not 100% sure if it's your problem, but 2.11BSD doesn't work on the
F11 chipset (11/23) because it doesn't have split I&D space.  You'll
need to use 2.9BSD or earlier on it.

 There are two versions of 2.11 if memory serves one with split
 I&D and one without. No.  2.11 **only** runs on SPlitID systems.  For non-ID
systems,
use 2.8, 2.9 or (perhaps) 2.10.  Ultrix-11 runs on all of these,
by the way.  AND is fully supported by VTserver, as I maintain
both :P 
Ok.  I only run V2.7 as unix without networking is limited 
usefulness to me.  I'd considered 2.11 on the 11/73 but never 
got to it.

 Correct, all T11 based systems, plus the /20, /10, /03
and I
believe the /04 dont have MMU, and are 64K systems. 
That was a statement on my part as I've designed with the T-11 and
have the full internal DOC set for that. FYI: the T-11 implmentation
in the VT24x added a MMU like the 11/23 sans PDR/ACF.
