Interactive Integer Practice- Missing APlusMath....

I found this...

APlus Math - Basic Skills Practice

extremely useful for 'some' students needing extra practice on integer rules...but it is no longer there...taken over by VarsityTutors and now they don't have the integer practice.

It was simple...almost a DOS like program.  Does anyone remember it or more importantly, have any idea where that code might be?  

As you know some students get very confused with integer rules.
