Yes. Is there the 50 pin cable from the M7555 to the dist panel?

3 QQ/CD and 5 QQ/QQ slots.

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.

What drive type? Fujitsu Eagle (14" and 8") where quite common. I have
seen several of them, but never with 3 phase PSU.

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.
