I played my first games on Atari 800XL http://en.wikipedia.org/wiki/File:Atari_800XL_Plain_White.jpg
It was a bit unusual coz we didn't use cassettes but 3,5" diskettes http://atarionline.pl/cn/data/upimages/LDW2000_3.jpg
I still got it somewhere in my attic.

In early 90' we switched to PC. The first game we played on our Pentium 100, 8MB RAM, 1,2GB HDD was Body Blows and Duke Nukem 3D. Since then PC was always my choice.

Ahh...nostalgia:)
