It has been tested with an Atari STFM.
The chip (IC1) is a 74LS86.
All resistors are 250mW 5%. C1 is a 100nF capacitor, the type and voltage rating are not critical, but I suggest a ceramic type.

I used the P9 power connector on the GBS-8200 V4.0 board to "steal" a +5V supply for this circuit. Red is +5V, black is 0V/GND.
Connect the Atari STF(M)/STE up as per the table below.
On the schematic diagram, the output is called "Comp Sync out" but in the table I refer to the same signal as CSync.
