This board replaces the PCB in the TV modulator to give a clear composite out display.
This will require that the TV modulator be de-soldered from the ZX81 board
Solder four wires to GND (I soldered it to the modulator shell as this is soldered to GND on the ZX81 board), ULA, A/V Out(centre pin of the RCA connector in the modulator), and VCC (+5v). Tune the picture to your TV using the two onboard trimmer resistors.
Use the switches for Back porch on / off as per instructions.
You are responsible for all soldering done to your ZX81.
