Ill try to remember the best I can!
Sega Master System
AMD Athlon 450Mhz Windows 98 PC
AMD Duron 800Mhz Windows ME PC
Sony Playstation 2
AMD Athlon 1.4Ghz Windows 2000 PC
The PCs get a bit hazy here as I've upgraded and changed so many times.
But it all built up to what I currently have -
Intel Core 2 Duo 2Ghz
Sony Playstation 3
I did have an Xbox 360 (Broke..broke..broke...and yes..broke again - FOUR TIMES!) I got rid after this lol.
Future systems - Amiga 1200? Hope so!
