When you say right hand side, do you mean (for example) pin 18 on UC3 and all others on the right hand side of the attached schematic?
Thanks.

In addiction to Marks's suggestion re: The chip selects, repeat the same address line process but this time looking at the buffered address lines BA0 to BA15 on the right hand side of UC3 / UB3.
Scope them to make sure the size and appearance is as expected and also that the frequencies mirror those of the CPU A0-A15 lines.
