Jack, I don't know because I have always used the 400 and 400 turbo. But, my guess is it would work with all of them. But, you have nothing to lose as the program is freeware and automtically updated.
So far, it has always been compatible with the SQL versions. If not, then my developer would likely make it compatible.
Since I have been using it (six years), it has cut my error rate down from ~ 7% to below 1% partly due to legibility.
But, I guess it would make it difficult to know which one to buy.
