The PCBs and backplane in the last photo are not standard 380Z boards. The 380Z 
doesn't use edge connectors like that, the boards just slot in guides and are joined 
by a 50 way IDC cable (which also carries power (!)).

To me this looks like an RML case that somebody has put an S100 backplane and 
a few boards in. I don't think it's an RML product (but would love to be proved wrong).
