Probably the best memory board for the atari is the one by Datafree
It is a 2.5/4 meg board that fits in 520's, 1040's and the 520stfm.
It is a 4 layer board so it will work in noisy environments (like 4 megs
on a 520stfm).  No other board works at 4 megs on ALL revisions of the ST.
The guys over at Supra Corp. use this board in their machines and are quite
pleasd.
