Yes they do work!  I just found out from AT&T that they do work
they have to be 150 nSec chips and you have to change the
switch setting on the mother board.  The setting is as follows

	Switch 0-1 off
	Switch 0-2 on
	Switch 0-3 off
	Switch 0-4 off

I looked at the Byte magazine ads and found out that these chips
are around $18-$20 a piece.  Considering how much it costs to buy
a memory board and that one expansion slot is wasted I think it definitley
is a good deal.
