This (along with Oregon Trail and Carmen Sandiego) were the things to use at my school.

I had no idea we had basically the first commercial version but the timing lines up.

As an adult I now feel for those teachers who had to hear a whole bunch of computers making constant sound effects though.

We had Kids Pix, then later Zoombinis, then after the Mac OS X update it was Marble Blast Gold (Nanosaur 2 was banned) and Kids Pix Deluxe 3
