From your first to resent, including with the experiences that came along with it...(1989 - 1992)
The Atari ST - My first personal computer, did more then just play games on it... (1992 - 1997)
A 1989 Toshiba "T3200" Laptop - My actual first PC with MS-DOS 5. I used this for writing many novels and playing Qbasic Gorillas for endless hours, though the "orange" screen-of-death was hard on the eyes...(1997 - 2001)
The 486 PC w/ Windows 98 - A friend gave me and what a piece of crap that was. Constant lockups and errors, hated that sucker, but dealt with it for two years until one morning: it died. Never heard the term "backup" so ya know what I was going though at that point... I took that sucker out and actually hacked it with a twin-bladed battle-ax (did I mention I collect Middle Age type weapons?). Yeah, my friends thought I was nuts, but they did mention something about getting "rid" of it, so I did... LOL(2001 - 2007)
A PI 246 w/ Windows 98 SE - A pretty decent computer (my first "attempted" self-built PC), never had any problems with it. It was the PC I did a lot of graphic designing and SNES emulating upon, though it's death in 2006 really hit me hard...(2007 - PRESENT)
My PIII 866 w/ Windows 2000 Pro - Never a complaint (my second "fully" self-built PC) and still running great to this day. Only problem I have is with Win2000's buggy "pain-in-the-side-as-a-thorn" networking problems. In all due time, just learned to work around it...
