I used Apple II (the original one) in 1982 in my geek kid class in 5th grade (82?). I'm 99% sure that's the first computer I used.

We had TRS-80s in middle school (maybe 84 or 84). We even had a 'network' - you could print by using a selector switch to connect your computer to the 'print computer'.

We didn't really have shit for computers in high school, though I did take a Computer Math class. This had a network of XTs connected to a central hard drive. Only time I used to do any hacking; we used to take it down out of boredom, and try to set something up that would cause the system to crash in a later period. Turns out one of the guys I used to do this with got a taste for real hacking -- ended up doing a stint in the federal pen, so I hear.

My university was run by Luddites, so if you didn't have your own computer you didn't have a computer to use.

Grad school had totally awesome compute for the time. A real nice Unix server + network for mathematical simulations. Plus, a T1 connection for the internet -- this, in 1994. Lovely.
