I do have the separator panel because I have the whole Graphite 600mhz iMac. After testing all the various pin locations with my multimeter it appears the PAV board is bad (tried the PMU reset etc, etc). So its up for parts.
My question now is about the separator panel. I was looking at an Indigo that I have that is missing the PAV and logic board already. I can see most of the screws but can't tell for sure if the crt needs to be removed. It looks like the iMac will need to be dismantled almost completely. Any insight?

However, if you do it as you suggest, you WILL fry your 600 MHz board by overheating it. The 400 MHz Motorola cpu board and all IBM boards (some 500 MHz and all 600-700 MHz) use a different perforated aluminum divider panel with a different heat sink design and location. The cpu on the 400 MHz will not mate with the IBM 500-700 MHz heat sink; and vice versa (including all 350 and 450 Motorola logic boards). I'll say it another way: There are no issues with this swap, EXCEPT you must use the correct divider panel with the correct heat sink for the 600 MHz board. Make sure you get the divider panel that goes with the logic board if you plan on a successful swap that will last longer than a few minutes after first boot-up. In fact, see if the seller will sell you the pair without first separating them. That way, you leave the factory cpu/thermal tape/heat sink mating surfaces untouched. Otherwise, get a new thermal tape before remating and installing. How do I know this? Been there, done that. Hate to see someone else make the same learning mistake and fry a 600 MHz board. -- Jim Scott -- The iMac List is sponsored by <http://lowendmac.com/> and...
