You are now ready to download your program into the EPROM.
After the programming operation is complete, PCbug11 will display this

PCbug11 defaults to base 10 for its input parameters; change this
to hexadecimal by typing
You must declare the addresses of the EPROM array to PCbug11.
To do this, type
Connect +12 volts (at most +12.5 volts) through a 100-
limiting resistor to P4 connector pin 18, the XIRQ* pin.
At the PCbug11 command prompt type
You should now remove the programming voltage from P4
connector pin 18, the XIRQ* pin.
Substitute the name of your program into the command above.
Use a full path name if your program is not located in the same
directory as PCbug11.
Each ORG directive in your assembly language source will cause
a pair of these lines to be generated. For this operation, $yyyy will
be incremented by the size of each block of code programmed
into the EPROM of the MC68HC711E9.
