just when i think im nearing the end of this build... one more road block.
i need my Performa keyboard (from a 6300CD with the single mouse port in the center) to turn on my G4 867Mhz quick silver.
i do not have an ADC video card, from what i have read pins 3/11 on AGP are in some way used to supply power BUT i cant find any info on HOW the ADC connector allowed the cinema monitors to power on the computer.
I have a wombat ADB to USB adapter. it has that side power button and allows use of the keyboard power button to turn on some computers. perhaps the wombat is reading the power button key press and that is something i could use? the QS has 25V stand by power, i could step that down to 5V and run the wombat internally - allowing for it to read the button press.
from there - what does the wombat do? it must be sending a signal down USB as its designed to turn on G3/G4's right? so if i put a usb sniffer in line off a daughter board, a separate PLC, i could wait for that packet to come down - when the daughter board's chip sees that packet - it could activate a transistorized relay which in turn could manually close the circuit for the front panel power button - thus allowing the keyboard to power on or off the QS.
what do you guys think, has anyone done this before?
an easier way?
maybe use an arduino in line to handle the relaying?
