Re: [PLUG] OT: SCSI controllers 4sale

According to sun's diagrams on boxes that I have, things should be wires
like this:

Narrow computer:

C - n - n - n - w - w - w

Wide computer:

C - w - w - w - n - n - n

That insinuates that if the wide things have a wide cable to the computer,
they can still speen in wide to the computer.
