I'm may only be missing it because I can't find it at all. It's on a hard drive (and backed up onto at least two CD-ROMs), but which ones? There are bloody millions of them, there's even a 40mb Seagate jobbie from 1991 and it still works.
So hmm, yeah, I've gone a bit nostalgic and I'm missing it a bit. The shrill whistle of the modem, the happy joyous sound of a successful handshake, Paul Dickie, my 3-year old son randomnly breaking into chat with random users, it were great.
It was also a pain in the arse and bloody expensive. The shareware version of Duke Nukem 3D took about three hours to download and cost a fortune because BT were money grabbing gits back then. Once had a phone bill for £400 run up simply by playing Legend of the Red Dragon (incidentally, I apparently held the world record for the amount of lays received in one game -- I may have even had you on the heart-shaped bed).
