Boom… the freebie frankenmac project is done. The free blue & white chasis I got from work, with a new (used) G3 Yosemite logic board, two sticks of 256meg ram from OWC, a Radeon 7000, and a G4 550 upgrade processor. I still had a few lockup issues, I don’t know if it was the old G3 processor which may have been damaged, OR the zip drive in this chasis. I disabled the zip drive cable connection the same time I put the G4 in, so I’m not sure which one killed the freezes. Right now, I’m running iTunes to stress the system and test the stability.
