I may be out of sync, too --- but don't be to quick to dismiss
this. Someone mentioned that the VME ethernet board had it's own
memory and was a memory mapped ... not bus mastering device. When I
had that board in my possession, I did note a grid of DRAM on it.
Probably about 512K to 1M of it.
So... the ethernet board would be more like a framebuffer than
a SCSI controller.
Dave.
