Custom Parts

Here are the custom-made parts I needed to complete the project. Many of these were made of sheet metal so they don't look pretty!

Power supply mounting plate

This plate is needed to adapt the ATX sized G4 power supply to the 9600 case.

PS Mtg Plate

Back plate with L-brackets for support

Momentary reset switch

As you can see, the reset switch will use an unused PCI slot on the back.

Reset Button

Momentary Internal Power Switch

This is mounted near the motherboard where the long plastic power button can press it.

Front panel wiring assembly

This is a tricky part of the project. I needed to make a connector for what would be to the front panel assembly of a G4. The cable was swiped out of an old 486. The power and reset switches are visible here, but I could not figure out how to get the power light working. You could use Ian Kalas' diagram from the G4 AGP to ATX case conversion article at to build the cable assembly or use the figure I made. The sleep contact must be grounded or else the computer will not go to sleep. I haven't made a switch for the programmer's button yet, but I included it in the diagram below.

I used my multimeter to measure the power-off voltages given in the diagram. I expected the LED voltage to be 3 or 5 volts when the power is on, but I only read about 0.5 V. The +5.0 V lead is present when the power is either on or off and when the machine is asleep.

The Power Light

Since I couldn't get the power light working using the front panel assembly, I built my own. This plugs into a drive connector and lights when the machine powers up. It doesn't light when the machine is in deep sleep mode, but I'm happy with it anyway. The LED fits into the power button. By the way, this is a 5-V blue LED in series with a 220-ohm resistor. It contrasts great with the OSX blue highlights and buttons!
