a KA820 is an 8200.  A 8250 is a KA825. Look at the processor
board, not the back panel.

To you get the three additional "console" lines do the following:

        $ R SYS$SYSTEM:SYSGEN
        CONNECT SLU=1
        CONNECT SLU=2
        CONNECT SLU=3

        This creates non-modem control lines called "TCA0",
        TCB0 and TCC0.

I have heard that these lines on an 82X0 processor are not terribly efficient
because they are serviced by the CPU microcode instead of an I/O adaptor
