A CPU corner wouldn’t be complete with some CPUs from competing camps. In this case, these are some Apple Computer CPUs from the IBM PowerPC days. Unfortunately, I don’t think there are proper socket designations for these, so hence they are lumped under the CPU architecture instead.
IBM PowerPC IBM2506K5319 933Mhz G4
This one was salvaged from a G4 Tower.
IBM PowerPC PPC750L-FB0B500 500Mhz G3
This one was a pull from a PowerBook of some sort, and so it seems to be a CPU, northbridge, VRM and RAM on a single module.
And here’s the same module without the SDRAM SODIMMs.
