I queried MPS since I don't see Bill Duvall listed as involved with
MPS, or at least listed here:

MPS, Macintosh Programmers System was the early name for MPW
(Macintosh Programmers Workshop)

"MPW was started in late 1985 by Rick Meyers, Jeff Parrish, and Dan
Smith (now Dan Keller)"

If it was MDS as you suggest then it would be good to have some
background to fill in where it came from, is it mentioned anywhere
else other than this?

It seems to lack a wikipedia entry.
