[comp.sys.atari.st] MFM hard drive question

stu892103@gcc.uucp (ATARI CORP.) (03/06/91)

     Fellow Atarians, I have a hard drive question.  I know that it is possible 
to use SCSI and RLL drives on the atari with the proper controller/adapter, but 
I would like to know if it is possible to use MFM drives.  I don't know much 
about hard drives at all.  I haven't seen any postings about this, so I don't 
care if replies are mailed to me or posted.  If I get any mail response, I'll
post a summary.  Thanks to any who reply.

It isn't any more difficult to hook up a MFM hard drive than an RLL. All you
have to do is get the appropriate SCSI to MFM or RLL disk controller board.
Adaptec makes both types. I don't remember the numbers though. Sorry.

            I think.

I have this setup on my ST:

ST DMA Port -> ICD Host Adaptor -> Adaptec 5500 -> MFM driver

Works very well.

MFM: ACB-4000 (2 drives) or ACB-5500 (4 drives)
RLL: ACB-4070.
