FidoNet

A worldwide hobbyist network of personal computers which

exchanges e-mail, discussion groups, and files. Founded in

1984 and originally consisting only of IBM PCs and

compatibles, FidoNet now includes such diverse machines as

Apple IIs, Ataris, Amigas, and Unix systems. Though

it is much younger than Usenet, FidoNet is already (in early

1991) a significant fraction of Usenet's size at some 8000

systems.
