I ran Fido on a DEC Rainbow in the early 80's.
Almost all of the BBS's were on PC's and accessed by telephone dial up.
Mail was sent by toll free zone hopping.

It was purely an amateur hobby thing.

The mini and mainframe world was too much of an expensive place for the
happy hobby hacker!!
Hence little or nothing by way of BBS's on PDP-11 and above.


Maybe in your neck of the woods. I had Unix in my house from 1984 on.
And, I ran a BBS (over a local lan using Sytek boxes which were serial
connections) at the place I worked, a campus.  Worked quite well.
