Need help configuring DZQ11s on 2.11BSD for VCF!

[Don North]

So if I run sysgen is /usr/sbin I get:

donorth[208] sysgen
Type device names one per line, optionally followed
by a comma and a repeat count.  Finish with EOF.
dz11,2
uda,1
tmscp,1
deqna,1
Table of standard DEC assignments for configuration:

  DEVICE     CSR   VECTOR
-------------------------
    DZ11  760070*  0300*
    DZ11  760100*  0310*
     UDA  772150   0154
   TMSCP  774500   0260
   DEQNA  774440   0120

CSRs and vectors marked '*' are in floating space.

So it looks like maybe the 2.11BSD autoconfig is only really finding 
your second DZ11 and not the first?
