  Pathetic indeed. The pdp-11/34a that I had when I was in high
school...I think I babbled about that machine at one point. I had a
DH11-AD mux in there (16 lines, modem control, DMA...a 9-slot
backplane full of boards), it had my terminal and another terminal in
the house, both running at 9600 baud, and a 1200 baud modem for
dialin...It would keep up with me and two friends using kermit to move
stuff back & forth, or hacking code (yay Swedish Pascal and DECUS C!)
with no problems at all...three sessions, two at 9600 baud and one at
1200 baud...simultaneously. Without even feeling the bump.

  Why do people use PeeCees, again? Pathetic, indeed.
