Windows ME?????
Try that OS or the little Linux systems floating around there, BTW, does it have a USB port? Or shop the net or yard sales or old computer stores, they usually have memory lying around that came from laps eons ago and glad to get rid of it for a buck or two. Did that with a few Dells we picked up and the kids are using them for Wrod, exel, etc and leaving the quality PC for the elders
