[G4] Processor Upgrades.

[Alastair W.Hendrie]

Hi Hal, thanks for the reply, and the offer.

I asked the same question of the Ebay seller, and he's replied as well. 
He says "There are physical problem with mounting the 733 processor on 
the sawtooth machine, the ide connector is  blocking it.  I have 
physically removed the plastic connector and I am now able to mount the 
DA processor.  But it would not boot.  I will trying to double check on 
the ram used and will try again. Meanwhile, sit back and wait for the 
good.bad news."

So at the moment, I'll hold off until he does a bit more testing.

Regards,

Alastair.
