The Lisa's external Profile hard disks (5 and 10MB) and internal
'Widget' hard disks both ran off of a parallel interface. I've not taken my

2/10 internal drive certainly appears to have been a custom setup. There
are like 3 circuit boards mounted above the drive assembly itself. I really
should put the effort into getting the Profile working but thought I'd try
to figure out this other setup first.
The board is from Sun Remarketing and is

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.
I'll take the cover off of the SH-204 and report the board ID once I get
home.
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 . .
If I remember correctly, the ST's interface was close to SCSI, close
enough that ICD created some relatively small interface adapters for it.
