SCSI adapter rumor?

[Jason Venner]

I have heard a rumour that there is an internal scsi adapter on the CPU
boards of machines like 3/160, 3/75's (same cpu), and all you need to make
scsi peripherals work with this card is a special cable that plugs into
the cpuboard.

Can anyone fill me in with more detail?
