The serial port is probably accessible using RS422 via the junction board that distributes power and signal to both clocks in the outer case. It is also available on the clock control board at RS232 levels (the signals are combined using combinational logic, rather than chosen with a switch). This is the small white 3-pin connector between the coin cell and the 2-pin connector for the front panel LED. Pins are ground, txd, rxd, counting from the edge of the motherboard towards the daughterboard.
