Hi Lucx,
I'm pretty sure that the BlueChip G4 is currently only for Lombard (and below). I figure the bus speed is the main difference, and I doubt you could just plug in a card made for the Lombard into your Pismo.
Not that I don't wish you could, I want a G4 in my Pismo SO BAD! (I have the same PB as you!) A couple of months ago there was a big rumour about Powerlogix coming up with a Pismo G4 upgrade...someone met some Powerlogix rep (or was it OWC?) at Macworld SF or something that implied that we would be seeing such an upgrade...but as it turns out, it was just a rumour, it could have been an ignorant reference to the BlueChip G4 we now see just for the Lombard...?
Anyway...my thought is, it will just be a matter of time before they release a BlueChip G4 for the Pismo...If the Pismo is 1 year newer than the Lombard, then we might just have to wait one more year from now...? Eventually all computers get upgrades, don't they?
Here's hoping I'm right!
