Indeed it does. I finally figured that one out last night
Needless to say all of the locations I examined came up filled with zeros.
However I sat down this afternoon to try and work out whats going on to
stop any of
my unibus controllers being seen.
Here's what I came up with
1. The same processor KDJ11-E can be used in a Qbus or Unibus system.
2. My monitor display does not work the same way as the manual shows.
3. Although the monitor display says Unibus system.
I suspect what I have is a CPU used in a Qbus system with a hacked
monitor and boot eprom.
For whatever reason they managed to disable the unibus I/O
I think the monitor Unibus detection was never disabled because
the module never went in one.
I know there is a V2 version of the Monitor
4. I have what I believed is a working 11/83 in my computer room
5 . I'm going to try my processor in there and yes I know about PMI and
Does any of this mean anything to you?
