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.).
I opened up my 5meg Profile hard disk finally and found that
it has a ST-506 inside of it coupled to a couple of Apple coverter
cards. Most of the case of those Profiles is taken up by the PSU.
At least that bodes well for eventually getting it running again if
the drive itself appears to be fairly normal. Without bothering the
drive geometry settings, if there are any, wouldn't any MFM drive
attached to this setup then appear to the system to be the 506?
