My first PC was a IBM 286 or IBM/AT, with 3 or 4 colors, and a few MB of RAM
I played Falcon on it (Falcon AT?) This One:
http://www.youtube.com/watch?v=rijiL8XfaVoFrom there a Packard Bell 486DX2, 16MB of Ram (trident 9680 PCI 1MB Ram Direct Draw GFX),
Then Intel 200MHz MMX, 32MB of RAM (Same GFX Card),
Then AMD 400MHz K6II 64MB of Ram (3dFX Voodoo 3/2000 PCI w/ 16MB VRAM),
Then 750 Athlon w/ 128MB of RAM, and ATI All in Wonder Radeon (7200 I think w/ 32 mb of Ram)
Then upgraded that System to a 1.1Ghz Athlon and two 256MB sticks (512mb total), then to two 512 MB sticks (1GB Total) then added the 256 sticks back to make it 1.5GB total), Then Upgraded to a Ati All In Wonder 9600XT (128MB)
Then Built an Athlon64 1.8Ghz, 768 MB of Ram, Geforce 4 MM 440 GPU
Then Sempron 2.2Ghz, 1 GB of Ram, ATI AIW 9600XT
Then Athlon II 3.0Ghz, 2GB of RAM, 8800GTS 640mb
then Phenom II 3Ghz, 4GB of Ram ATI 5830, which was replaced with a AMD6850 under RMA.
then FX-8120. with 16GB of Ram, w/ AMD7950 3GB
I remember coming out of one of those PC conventions with 2x512MB Dimms, and rushing home to install and go on the PC irc channel and flash them with my /systeminfo script, as 1GB of Ram in 2001 was A LOT. Now i Have 16GB.
