Silly random thought. IIRC, there's an empty 40 pin DIL socket on the ACW 
coprocessor board, and I think it's on the 32016 sencond processor board 
too (I must come and collect that from you). Wasn't that for an MMU chip? 
If so, it may have been needed for unix/xenix, but not PANOS (I've never 
seen a 32016 board with it fitted).

Considering how few ACWs wer made, I find that unlikely. I've never seen 
a 32016 second processor or an ACW running anything but PANOS.
