I have two desktop beige G3s. The cases are breaking down, and every time I open them, something breaks off. One has a motherboard that appears to be non-functional, I can't get it do anything, although the power supply, the RAM, PCI cards, and everything I had in there appears to be good. I do not know if the other is functional. I've stripped them of everything but the MBs. I don't have the equipment or the expertise to test traces and voltages. Since I am preparing to retire from this job, I have been encouraging the move to Sawtooth G4s. Is there any value in these MBs, or should I just leave them in the disitegrating cases and take them to the local recycler?
