Dear comp.sys.mac.hardware,

I'm trying to put a DEC DSP3105 3.5" hard disk drive into an  old
Macintosh  II.   Unfortunately I have not succeeded. MacEnvy will
spot "something" on SCSI ID 1, all formatting (Apples  HD  Setup,
Norton  Utilities,  and  Microtech's  HD Formatter) software I've
tried failed to recognize the drive. Microtech's HD Formatter re-
ported the following when moving the cursor over the "ID 1" radio
button:

Device Manufacturer:   'DEC'
Model of Device:       'DSP3105S'
Device Revision Level: 'T368'

But it would not enable the format button.

I can see BSY LED flash (which is NOT equivalent to the SCSI  BSY
signal)  whenever  I  try  to  select the drive (using any of the
above SW).

Below is some spec on the drive and a MacEnvy report of the  sys-
tem. SCSI ID 0 is a Microtech drive which is working fine.

Have anybody used a DEC DSP3105 on their  Mac  or  is  there  any
(hopefully   ftp'able)  generic  formatting/driver  software  out
there. Oh, BTW I installed two DEC DSP3105's in my  SPARCStatsion
II without any problems.

Thanks in advance, regards Petter Gustad
