Once you have obtained PCbug11, use this step-by-step procedure.
Apply power to the programmer board by moving the +5-volt switch to
the ON position.
From a DOS command line prompt, start PCbug11 this way:
PCbug11only supports COM ports 1 and 2.
PCbug11 defaults to base ten for its input parameters.

Before applying power to the programming board, connect the
M68HC711E9PGMR serial port P2 to one of your PC COM ports
with a standard 25 pin RS-232 cable. Do not use a null modem
cable or adapter which swaps the transmit and receive signals
between the connectors at each end of the cable.
Place your MC68HC811E2 part in the PLCC socket on your
board.
Insert the part upside down with the notched corner pointing
toward the red power LED.
Make sure both S1 and S2 switches are turned off.
Apply +5 volts to +5 volts and ground to GND on the programmer
board’s power connector, P1. Applying voltage to the V
not necessary.
