I can't watch this go by any more..  :^)

(recently posted items along this line NOT included.)

ALL of the IBM model 60 and 80 PS/2 systems we've looked at have had

ESDI INTERFACES, NOT MFM.  

The connectors used in the IBM box ARE JUST like ST412/506 MFM guys, 
you know, one of them 34 pin the other 20 pin, but are ESDI..... 
AT LEAST ON OUR MACHINES.

To find out what you have for a controller, run you reference diskette.

Look into the change configuration options, select the one that talks about
viewing your current configuration, use the up/down arrows and get to 
where it shows your drive configuration.  IF it says MFM=it is, if it says
SCSI=it is, and if it says ESDI=it is.

Let the machine tell YOU what IT thinks it has.  Relying on connector
familiarity is not always going to work.

have fun

later
