I have an IBM PS/2 mod 60-041.  This has a 44 meg mfm drive.  I need more
disk space.  Another IBM HD is very expensive.  Compatible drives by other
companies like CMI are also some what expensive for such a small slow drive.
I would like to get a faster ESDI or SCSI drive.  I guess I could get an
ESDI controller like used in the mod 60-071, but I think something from
Adaptec or Western Digital, stc might give better value.  Can anyone help
me with the following?

Has anyone used a controller other than IBM's in a mod 60?  Whose and how
did it work?

Since the mod 60 uses software to setup the configuration, how could I get
the computer to recognize a non-IBM controller and disk drive which did not
have the IBM fingerprint or identifing information builtin?

I would like to get a HD disk of about 200 megs and 16 - 24 ms access time.
and a tranfer rate of 10 or 15 which is most economical and reliable.  Any
suggestions of solutions that have been used successfully by others would be
appreciated.

Could I get an IBM ESDI adapter and use some disk drive other than the IBM
71 Mb. drive?
