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

11/23 is based on the F11, and therefore does *not* have SplitID
(11/40,34,50,55,60,23).  The /44, 45, 70, 53, 73 and up do.

Correct, all T11 based systems, plus the /20, /10, /03 and I
believe the /04 dont have MMU, and are 64K systems.
