G3 iMac logic board swap

[dolph]

I have the opportunity to pick up a 700 MHz logic board from a G3 iMac SE 700 with a dead CRT, would like to swap it into my DV SE (500 MHz). I know the PPC chip is slightly differet - 750cx on the 700 MHz unit, 750 in the 500 MHz unit - will I need to do anything special to my 500 MHz machine to use this new logic board? Power supply will be sufficient?

These boards have the ATI Rage Ultra 128 graphics with 16 MB of VRAM built right onto them right? I think I read that somewhere...

Yes, it's probably a waste of time and $ for so little of a speed bump, but I'm kinda bored at the moment and need a new hobby.

Thanks!

Are the ports on the sides of the iMacs identical?

Yeup, they're the same form factor, "iMac 350".

I wouldn't say it's a "tiny" speed bump -- it's actually gonna be 1.4 times faster (roughly 30 - 40% faster).

If the logic boards and form factors are identical, it should be a direct swap -- and yes, they use the Rage 128 chipset.

Let us know how it goes!

While we're on that subject, could I do the same with a iMac 350?

I know that there is no firewire on a 350 and that there is on a 700 but must be easy to overcome.
