My first computer was C64 that I got from a friend in 1994, and it didn't work at all, so I couldn't use it.

LOL
5 months after I got a 486DX2 66Mhz PC, and it was my first computer then. Imagine, I used it until 2002, upgraded to Pentium 100 though, before I got the current P4 2.4Ghz, now upgraded to 2.8 Ghz.
