  Earlier today I posted a response to a question about a Seagate
controller. That response was correct, but incomplete. He is the scoop
on Seagate hard disk controllers for AT style machines.

model		type*	format	intrlv.
1003VMM1	HD	MFM	2:1
1003VMM2	HF	MFM	2:1
1003VSR1	HD	RLL	2:1
1003VSR2	HF	RLL	2:1
1006VMM1	HD	MFM	1:1
1006VMM2	HF	MFM	1:1
1006VSR1	HD	RLL	1:1
1006VSR2	HF	RLL	1:1

*HD is HD only, HF is 2 hard + 2 floppy

The format is 100nVxxy
                 | | |
		 | |  \__ 1 HD only, 2 hard/floppy
		 |  \____ MM - MFM, SR - RLL
		  \______ 3 - 2:1, 6 - 1:1

This is from a spec sheet from a wholesaler.
