I was around almost at the beginning of Eternal September. In December of 1994, I posted to a newsgroup that google eventually archived on the web. Beyond that, my eBay account predates y2k. The first purchase I recall was a parallel port ethernet adapter so I could use Arachne for DOS on my 386SLC33 laptop in the university library. I mailed out a money order and hoped this "buying shit on the internet" thing wasn't going to be a scam.
