Actually the backplane has BNC ethernet. Earch data mover besides having 
it's regular shit:
P3-700, 512mb ram, quad ethernet, emulex dual channel fc/al card, 
mainboard by motorola
dual 10mbit 3com nic???
The AUI connector connects to the power supply board that uses a lucent 
dc/dc converter
then goes onto the backplane and from there onto a BNC network.

I guess that way they dont have to use a network switch. But why dual 
controllers per chassie.

Also I have not found any IDE or SCSI drive anywhere. Going to 
investigate a bit further. The
controll station had a floppy in the inside too.
