    Apple

    The first appearance of DDR technology in Apple computers was not in main memory,

    but in the form of the backside or ‘L3’ cache interfaced to the Motorola PowerPC G4

    7450 CPU. The early Apple processor design utilized 1MB of DDR cache (the

    PowerMac G4 733 using the Digital Audio motherboard.) Other designs use 2MB of

    DDR cache for L3, although some of the recently introduced Apple offerings have moved

    back down to 1MB of L3 DDR.

    According to this, the only FW800 processor with 2MB of L2 cache per CPU was the dual 1.42GHz.

    You can also use the dual 1.42 in a non-FW800 MDD.. I have done this myself when I used to own one and it ran just as fast.. My original processor was the Dual 1.25 w/2MB L3 Cache, so there were 2MB L3 cache dualie 1.25's.

    It's the Logic board, faster CPUs can boot OS9.

    Sorry didn't get back fast enough.. Yes, even if its a 1.42 and the logic board is non-fw800.. it will still boot into OS 9 without any problem.. The FW800 is the hardware and the chip which prevents it from booting into OS 9 as OS 9 does not support FW800.

    That is truly despicable.  An incalculably GREAT LOSS for this forum.
