14 years is a little before the date myself and coworkers say "all these kids ruined the internet" (around 2002?)
when i started work in the mid 90s the (software/hardware) company i work for had a compuserve and a single 28k modem, and a handcoded BBS, one of my first jobs was (to my disappointment) to set up some swanky BBS software. to go on the internet we had to basically take remote ownership of the modem using com port sharing software and go "online" which stopped the bbs and stopped all incoming email. time online was precious.
in under 5 years the world changed, went from not having a modem at home to those "flat rate 24/7" ones to having a guy come out and fit adsl!
never did demo's though just individual things, but one of the things that went down well at my job interview was my talking about the messing around i'd done with talking to a soundblaster card by making my own dos library.
Looking at my old code a few days ago I found on a caddy (some 2d directdraw and opengl) the dates were from late 1999! thats how long ago I last touched code with any intention at home, and how long I've had ideas bouncing in my head! I think what helps is that i've now got a dedicated, uninterrupted space to code in (I converted the garage and have PC/xbox360/big tv/guitars

)
I think i went for GL even back then because of GLQuake and because I had an Orchid Righteous 3D card. The Nehe stuff even goes back that far, I have comments referring to them!
I used to be all over
www.hornet.org which looks like it closed '98 - there were folders and folders of source in there on every subject. I've got a copy on my caddy, but it looks like it can found here too
ftp://ftp.scene.org/mirrors/hornet/code/I do wish I had an earlier start at coding, I always
wanted to but didn't have any support. I didn't meet people like that until college which changed my path.
I *think* I met two guys who were c64 sceners when I was really young like 10-12 years old. (one only lived 2 doors down, i believe he was good at maths and was later he was my judo instructor for beginner classes, but i progressed beyond that class eventually).
I also knew someone else who had amiga scene connects and would meet to swap (mostly game) disks in motorway services, that would have been caround 1993.
