To write the eeprom, you need:

Put the male ends of the wires into the dip28 socket.
Put the female ends of the wires onto the test clip.
Put the dip28 socket into the zif socket on the programmer.
Remove the Teeprom from the Model 100/102/200
Clip the test clip onto the chip on the Teeprom module.

Similar to FigTronix#Model_100/102/200_Option_ROM_adapter_(SOIC_28C256), but without the write-enable jumper and special programming adapter.
