Hi all,
finally I got my real Iron delivered. I nearly can't express how happy I am
about that.
Now the usual Inspection begins (PSUs etc...)
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
Looks OK to me, though I'd point out that the priority is daisy-chained; you may want
to consider moving the DELQA further up the chain (or so it's been recommended to me).
Someone else may be better able to comment on that.
Since the DELQA is a dual-width, you may get some mileage putting it right before the
DLV11 (assuming you have a serpentine layout at that point on your backplane, it'll
help you fill out the pair of slots, and serial interrupts probably ought to be lower
priority than Ethernet, but higher than the disk). You didn't mention what backplane
you're using; the BA23 backplane has 3 quad-width slots of straight-through plus CD,
then the rest are serpentine.
Congrats! Enjoy! It should be easy enough to tell if everything is at least working by
probing the CSRs with ODT.
