I'm getting really confused. I thought the majority of what came off the 
board went to the ATLAS backplane.  We only needed a couple of 
connectors or controls to the "outside world" - DE-9, USB, LEDs, encoders...

A 96-pin backplane plus a 68-pin SCSI connector plus a 64-pin DIN 
connector plus a USB connector on a 4" square board -- where do we put 
the parts? :-)
