Need help configuring DZQ11s on 2.11BSD for VCF!

[Don North]

When I brought up my 11/44 with 2.11BSD I also had to fiddle with the 
/etc/dtab file, which allocates CSRs/VECTORs to devices (ie, tells the 
s/w what you did to the hardware). Your second DZQ is probably being 
probed by s/w as a floating device (160070 ??) or at least not at the 
address you have the h/w set to.

I had to change the /etc/dtab entry for my first DZ11 to 160100/300 from 
160100/310 to be compatible with SIMH (I don't configure the TU58 at 
176500/300 under SIMH and/or 2.11BSD).
