Need help configuring DZQ11s on 2.11BSD for VCF!

So if I run sysgen is /usr/sbin I get:
Type device names one per line, optionally followed
by a comma and a repeat count. Finish with EOF.
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?
