Mine was a 6502C CPU in an Atari 65XE
It ran at 1.77Mhz in PAL or 1.79Mhz in NTSC
Had 64K of RAM
It was a cut down version of the 130XE which had 128K Ram
I remember it well, it loaded games from a casette tape drive.
for it to load the game you got the system ready and then pressed play on the tape drive you had to wait for the sounds from the tape to load into the systems RAM.
upto 60 or 90 mins before you could play a game.....LOL
The joy of my youth.......
then it was games consoles
Master System II
Game Boy
Until i got a PC running an Intel P120Mhz Packard Bell from Dixons £1500 with printer & 5yr OSM..... Rip off but Awsome LOL
Then PII 400Mhz (Built Myself)
Then AMD Thunderbird 1Ghz (again Built myself) "The AXIA chip" fully unlocked could clock to 1.6Ghz at a real push but very unstable and I cooked it running Half Life......LOL
Replaced it with the same CPU but ran it at 1.4Ghz Safely...AWSOME CPU
Game Console PS2
Then back to Intel P4 3Ghz (yes built it myself aswell) - Still have it, runs as the basic family PC for the kids.....
Game Console Xbox 360
Now on the Intel i5 760 2.8Ghz Quad Core (My New Gaming Rig just Built it Dec 2010)
Plus the Laptops I've had in between
IBM Stinkpad - Intel P4 Celeron 2Ghz
Samsung P55 - Intel P4 2.66Ghz
HP Probook 4510s - Intel Core 2 Duo T6570 @ 2.10Ghz (Currently Still Use)
Wow what a history there..... I can't belive how many I've been through....

I'm only 29 and all that spreads from 1986 onwards... (ok some of the early ones parents bought for me)
