    iMac G4: How did people optimize it for making music? (MIDI rec latency issue)

    I'd like to occasionally use my G4 for musical drafting. I put an SSD into the iMac recently, but haven't updated the RAM from the 1GB it has now. I probably will eventually, but somehow it feels like it's not the culprit, or that it's not the only culprit to the issue. The issue is that even...

    Between 2 iMac G4 17" Logic Board models numbers

    Hello all! I've started to refurbish a iMac G4 17" and got stumped at logic board replacement. The model number for the board is 820-1501-A but there are two sub model numbers associated with it, 661-3001 and 661-2954. Can these two be used interchangably? yakult121

    After the USPS losing my iMac for two months, it's finally here! I ordered it to replace the 17" one I've never been able to make work.

    iMac G4 won't boot, fan twitches

    Alright guys, so I'm having some troubles with an old flowerpot iMac. About a month ago I knocked a glass of water on the desk where the computer is sitting.

    iMac G4 - 160 or 180 Watt PSU?

    I just picked up a 17 inch iMac G4 cheap on Craigslist, model number M6498. It doesn't work, and from what I've been seeing, the problem is most likely to be the Power Supply. When the power button is pushed, nothing happens at all, not even the fan spins up. Is this the power supply or could it...
