I was meaning to respond to a message you wrote a couple weeks ago:
the the sys 460 is a two rack system - 1 rack had the
diablo disk drive,
hard drive and i/o comms interface (i have all of those components and
alot of spare cpu and terminal pcb's).
the other rack had both the iv 70 and iv 90 cpu's in it.
This sounds an awful lot like what I have.
the iv 70 had a card in it that passed the backplane
signals to the iv
90 - i don't know why they used this "dual cpu" confg.
Check out this picture:

On the left is the CPU cabinet. The top is the IV/90 CPU (presumably).
The section below contains more boards. I haven't looked at it so long
that I forgot exactly what's in there.
On the right is the tape drive (top). I forget what is directly below it
(the aluminum thing). Below that is (I believe) the communication
interface.
I'll have to give a look at it this week to refresh my memory. I'm closer
to being able to access it again because of the move.
