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.
