...AFAIK, the Shimano cog spacing is all the same Within a specific number of rear cogs....even with the early DA stuff. Where DA was distinct from the other Shimano stuff was in the DA pull ratios in the shifters and rear derailleur. So If something says it's compatible with Shimano, and you have a Shimano cogset on your rear freehub, the combination should work.
It gets more confusing if you try it with a freewheel. Early Dura Ace worked very, very well. It was just designed intentionally to not work mixed with the other Shimano component lines, like 600.
