1st :- Spectrum 48k, Came out in 81 i think and was a taped based loader pc. wait 45 minutes for a game to load that would consist of 2 dot and 1 bigger dot chasing each other that would normally crash 2 seconds into the game, ah the memorys.
2nd :- Spectrum 128+3, this at the time was the daddy, floppy disk based and basically the same useless piece of junk, still have this in a cuboard somewhere.
3rd :- the good old trusty nes, My mate had one long before i did and many a hour where spent blowing on cartridges trying to get them to work.
4th :- Super nintendo (super famico in usa), Still a dam fine system even to this day, some of the most awesome games ever released where played on this and still as much fun as anything out today.
5th :- Dreamcast, i owned it ... don't remember much more than that other than it was my first time of surfing the internet i think, Honestly don't know what happened to it.
6th :- Ps1, can't remember what i did with this.
7th :- ps2, Still have this and about 50 games that are not worth selling but i don't want to throw out.
8th, 9th , 10th and 11th, Xbox 360, seems to commit suicide a lot and just die on me ... last one is holding out strong.
