Lets see I used an Apple II which I kicked ass at Lemonade Stand and I used Windows 3.11 and then 95 and I may have had a run in with 98 at some point and now I use XP SP2. I know I played around with DOS somewhere in there to.
Many of you here starting from DOS. How about the computer brand that you use for the 1st time? I can't quite remember the one I use in 1993. But at that time, the familiar name that I heard only IBM and Apple.
