BA23 number 2:
Front bays: an RX50 (minus cable - a PC floppy cable shouyld do the job

Yes. Is there
the 50 pin cable from the M7555 to the dist panel?
Now to me, that doesn't look right. The BA23 is
QQ/CD for the top 4 slots
and QQ/QQ serpentine for the bottom 4 - right?
3 QQ/CD and 5 QQ/QQ slots.
So basically, any pointers on how this might have been
configured
I an afraid to say that it seams that there are some cards from BA23 #2
are missing. So you will not be able to restore the old config. But it
seams that there is enough to put a well working config together. Start
with identifying the Emulex cards. (I did not find any infos grep-ing
the field-guide.txt.) Be happy to have a TK70. It is much better than
the TK50. And a 9 track drive is always nice.
It looks like one of the HDD's (both are SMD) has
a 3 phase PSU -
What drive type? Fujitsu Eagle (14" and 8") where quite
common. I have
seen several of them, but never with 3 phase PSU.
Oh, and what's J6 on the BA23 PSU for?
Power controll. I saw this on a rack mout MVII: A cable from J6 to a
power distribution box that contained a relais. This relais was driven
by the power from J6. The BA23 was connected to a "unswitched" socket of
the power distribution box and the rest of the rack to the "switched"
sockets behind the relais. So the entire rack is powered on by powering
that BA23.
