I noticed. :-(

Yeah, that was poorly stated.  The Model II and its decendants had
their own bus, but used the MIII thing for hard drives, right?

Hum, how do you handle that?  A switch box, or do you physically move
the cable?  Do you manually run getty when you need it, or is it
running all the time?  I once used a 4-to-1 switch box to tie several old
machines to a linux box's serial port, but I had problems with the
machines maxing out at different speeds, and if the machine on the
other end was off, getty was picking up line noise and trying to log
it in! :-(

I know what UUCP is, but I've never set it up or explicitly used it.
