Could please one of you have a look at my "board-layout" in the backplane
and correct me if I am completely wrong?
From top downwards I would insert the modules as follows:
M8189 - 11/23 -CPU
M8067 - MSV-11 - 256 KW RAM
M8043 - DLV11 - Quad Serial Card
M8061 - RLV12 - RL02 Controller
M7516 - DELQA - Ethernet Card
What backplane do you have? For example you might have one of the DEC
backplanes below:
H9270 4 x 4 backplane (four rows of four slots)
H9273-A 9 x 4 backplane (nine rows of four slots)
H9275-A 9 X 4 backplane (nine rows of four slots)
H9276 9 X 4 backplane (nine rows of four slots)
H9278-A 8 X 4 backplane (eight rows of four slots)
If you have a BA23 box you should have a H9278-A backplane.
Goal is to bring this System up with VTSERVER for
starters. I hope to add
one or two RL02s in Summer. A RX50 and a RD50/51 or 52 (don't remember at
the moment) are sitting on my shelf too and I'd like to put them in there.
But first I have to get a controller for that.
If you have a BA23 box it should have the distribution panel for an
M7555 RQDX3 so then all you need is to find an M7555 plus the cables,
which shouldn't be too hard to find, to use your RX50 and/or RD5x
drives.
