Ah, I see. It's some whacko custom thingie. Didn't the Lisa originally
use some kind of ProFile-ish thing (custom interface, custom drive
electronix, etc.).

Hm, very interesting! I wonder what model they used? Like I said
before,
most of the early SCSI boards from Adaptec (and most of the other mfr's
as well at that time) were only partial SCSI implementations.

Ah, well, mebbe I stuck my foot in my mouth-- the ST did have a SCSI
interface, didn't it? Or was it yet another whacko custom thingie . .
