My first computer was an IBM PS/2 Model 55SX running MS-DOS 5.0 that I bought new in 1991. I used that computer mostly for games until 1997 when I acquired a Windows 95 computer. I later upgraded to Windows 98 and ran that until a couple of years ago when the hard drive crashed. I gave it to a guy I knew to fix it up for me, and he in turn built me a whole new PC from scratch with an Athlon XP 1500+ and Windows XP. It still runs alright, although it has been giving me quite a few problems lately.
