-X68000 has inverted power-on signal and [[http://nfggames.com/nfg/x68repair/|Power Supply Replacement]] suggests using an invertor IC (a [[http://nfggames.com/x68000/Documentation/Datasheets/74HC_HCT04.pdf|74HC04]]) and a resistor (4.7k Ohm). For a smaller solution and less soldering you can use [[http://nfggames.com/x68000/Documentation/Datasheets/2N7000.pdf|2N7000]] N-channel MOSFET instead. Connect 'source' to ground, 'drain' to the ATX 'PS_ON#' pin, and then the yellow wire from the X68K to 'gate'.+X68000 has inverted power-on signal and [[http://nfggames.com/nfg/x68repair/|Power Supply Replacement]] suggests using an invertor IC (a [[http://nfggames.com/x68000/Documentation/Datasheets/74HC_HCT04.pdf|74HC04]]) and a resistor (4.7k Ohm) with the replaced power supply.
