The system actually dates from 1985 or so. I'm aware it isn't "the first" however it is one of the first BBS systems that:
* Was privately owned (not Compuserve or a university computer)
* Had 5 simultaneous dial-up connections.
* Was designed for and used mainly by non-computer people.
There were plenty of single-line BBSs at the time but very few multi-line ones that were available to the general public.
This system used the general BBS structure made popular by the CDC Plato system back in the early 1970's.
The machine only has a 5" floppy and I don't have any disks for it, or a drive that will work on a PC, so that's out.
My main question remains, does anyone know what file system this machine used?
I'm aware of kermit and X,Y,Zmodem for transferring stuff but I was hoping to avoid going that route. The ports on this thing are only 9600 baud so even this relatively small transfer would take awhile...plus I was hoping to avoid building/buying custom cables that I'll only use once. Pulling the hard drive is easier, so long as Xenix used a file system that modern Linux can read.
