It's a 0665-38 by the numbers you've added. That means it's a 40ms access, 31mb MFM (ST412/506)
interface drive. It can't be SCSI obviously by the 2 sets of connectors, only MFM, RLL or ESDI.
ESDI is out by my reference. It should be hooked by MFM specs to an MFM attachment card and the
settings set to 733 cyls, 5 hds, 17 sectors per track. Make sure it's set as the proper unit as
well. If it's the primary drive on a twist cable (the 34 pin cable) then set it to DS1 (B:) like
you do floppy drives.
