I bought a Dual G4 1.0GHz MDD from Free Geek Minneapolis for $10 before the PPC 2024 Challenge. It never powered on. I built my own ATX power cable adapter and I got it to power but never chime. I just purchased a dual 867MHz mobo/daughter from eBay and swapped it out. It booted fine. The original was a 167MHz motherboard, and the dual 867 is a 133MHz motherboard. I noticed that when I removed the heatsink on the 1.0GHz, there was some burnt residue and the PPC chips had some dark corners. So, just to play around... I found the tables.
I down graded the bus speed on the 1.0GHz daughter (red) to 133MHz, and set the clock to 933MHz (yellow) just to test it out on the 133MHz motherboard. Still no boot chime or video. So the dual 1.0GHz daughter is dead.
I upgraded the dual 867MHz daughter to 167MHz bus (blue) and slightly overclocked it to 917MHz (Green).
I still have to revive a couple of my PCI-SATA cards to put an SSD in here.
