<I bought mine new as a kit in '83, as part of the first production run.

Mine is only slightly later, has the 5380 scsi chip.

The sequence of disks over the years for the HDD side:
xybec and st506 bought new in 82(late). Still have both.
Adaptec, and Quantum D540 (31mb) much faster.
the adaptec died and the xybec was in with a st251 for a while
then the fujitsu 3.5" scsi drive.

Here we go again... I DIDN'T SAY IT WAS IDE. I said it was similar in
respect that it was a bus level interface for a controller and predates
IDE. I do know that the wd1003 was what the IDE base design was patterned
