OK got PCB #5 figured out now.
The Motherboard for this is the AA017742A, with two daughterboard alternates:
Alt 1 - Board coded SVO00714A + SVN00003A, uses all discrete TTL ics for the Bit Shifter function
Alt 2 - Board coded SVO70001B + SVN00001B, uses 25s10 ics in conjunction with discrete TTL ics for the Bit Shifter function
