Re: BBS software for the PDP 11

I too wrote half a BBS back in the early 80's for MU-BASIC on RT-11v4 when I was in mid secondary school. I ended up running GBBS on an apple2 instead. That seems like a lifetime ago :-) BTW this is my first post to the list, so, I'll introduce myself. I'm a C# .net developer these days, but, I

Well, that would depend on the OS in use. There are BBS programs for Unix. I used one that came from one of the sources newsgroups decades ago and it worked really well (I never tried on a PDP-11 but there was nothing in it that would preclude this. I did it on a SYS III Xenix clone). BSD 2.11

I know of several very different PDP-11 BBS's using very disparate architectures. Some were run on RT-11 or RSTS-11 entirely inside a BASIC program that managed every element of call answering, logging in, and disconnection. And others took advantage of TSX-11, RSX-11 and RSTS-11 login
