BBS stands for Bulletin
Board System. Before Google, before Twitter, before YouTube,
before EVERYTHING you do with a web browser or an app... there were
computer bulletin boards. Think of a BBS as sort of like Discord,
but you could do more than just read and write messages. You could
have online games (called doors), you could have files to upload and
download. You could chat with other users. And it was a lot of fun.
To access a BBS, you used a telephone modem and a DOS terminal program.
And of course if you called bulletin boards that were far away, you
had a big phone bill. I ran one myself for 5-6 years, called The Lost
City. The BBS software and everything I used for the BBS were DOS
programs. My computer didn't even have Windows on it. It didn't even
have a hard drive! Everything was stored on a couple of large floppy
disks. When people called the bulletin board, I could actually hear
the disk drives grinding.
Guess what. Computer bulletin boards are back!!! And I think there are more of them than ever, but most of these boards are run by old guys like me who used to run bulletin boards back in the early days of the Internet. We need users. People like YOU. It takes a while to get used to these bulletin boards, but once you get the hang of it they are fun to use. And these days you don't need a telephone modem to call them because you can access them through the Internet using a special protocol called Telnet. So no more big phone bills. If you have Internet access and a computer, all you need is a terminal program. Actually you don't even need that, but the terminal program makes it a lot easier.
Don't expect to see fancy graphics on computer bulletin boards.
They use graphics called ANSI, which is similar to ASCII, but constructed
from a larger set of 256 letters, numbers, and symbols —
all codes found in IBM code page 437, often referred to as extended
ASCII and used in MS-DOS and Unix environments. In other words,
ANSI graphics are pretty crude, but hey, you can create ANSI art
with DOS.
