This one's still alive and kicking in web/telnet form as a Mac-oriented BBS, and was alive and kicking as a Commodore 64/128-oriented BBS long before the info you see below. This was the first board I ever called as a wee sprat (whereupon connecting, creating my new user account, and getting verified, I also behaved like a wee sprat, but I like to think of that first year of BBSing as "practice"--I digress).
My uncle had given me his old Commodore 128 setup to play Impossible Mission and other such great classic games on, and in the box of miscellaneous peripherals he had collected over the years, there was a rectangular box with the name "modem / 300" on it. Naturally I had to try to make use of this thing.
The elementary section of the school I went to at the time was still using Commodore 64s (with datasette drives!) for teaching spelling and pronunciation of words. So I talked to my high school principal (I guess he could be referred to as the "sysop" since he was always fixing the things, yuk yuk), and he did some digging and found the number to this Commodore-oriented BBS. What followed was, literally, my entire life since. If I had never called Headgap, the string of events that followed that led me to the life I have now (including my current friends, girlfriend, job, and almost everything else) never would have happened.
Incidentally, Amadeus recently made it a point to expound on his pivotal role in the history of my life--some time into my BBSing years, he sold me and came to my house to install an [ancient and otherwise, for a young teenager, prohibitively expensive] RS-232 interface and 2400 baud modem for my little Commodore. Boy, how did I live at 300 baud for so long before that. Thanks, Ama. ;-)
It's funny thinking of a time when a half-gigabyte of storage was "a lot" and two (wow, two!) CD-ROMs was amazing, and both were drawing points for potential users.
