You're right of course. Unlike the others I've worked with (11/04, 11/34,
11/03 and 11/23) this one include a serial port. Hasn't worked with CPU
boards yet so I forgot the built-in serial port.
BTW. I do have omnibus, unibus and qbus stuff to trade with if there is
interest.

The plan is to get it to work with the 8kW core memory, M7800 connected
to
a good old teletype and PC05 paper-tape reader /
punch and then run paper
tape BASIC on it or other paper tape software.
The problem is that I am lacking in the M7810
board. Since I do have a
M105
and M7821 a M781 could do as well.
Why do you need a second serial port? The PDP11/05 CPU board set has a
built-in
UART set to the console port address. In general it was set to be 110
baud, and
has a current loop interface, but that's just what you need for a teletype -tony
