I know I need to use an IDE CD drive, but does anyone know how the back panel works (I need to know what the pin out is)?

Can you explain more specifically? I have both 5500's and iBooks here in pieces, so I can show you whatever you need...

Thanks for the reply. If yo look at the logic board, you can see the large connector. I was looking for a list of where each pin goes to. I ment to put iMac, not iBook in the title . Sorry

Ah okay, I can't help you there, and I fear this will be largely in vein. You should try to remove that adapter from the equation, if at all possible; it will complicate things massively.

Have you got the Apple documentation on the 5500? If not, I can let you know where to get that, but as I said, unless you have advanced skills in electronics, I wouldn't bother.

I quite like your inadvertent iBook idea though. I have a few 5500's here currently out of service, and a headless iBook. It'd be very easy to slot the iBook into the 5500 mobo housing, crank the 5500 top-fan up a bit to cool the area, and hook a new short-neck CRT up to the iBook via the VGA dongle. Interesting...

That would be cool. Would you replace the SCSI CD-ROM with an IDE DVD RW drive in place and wire it into the iBook's IDE bus? If you could, I'd like the documents about the 5500. Is the display a standard VGA monitor or is some wierd type?

Gimme an e-mail and I'll send you the documentation - exsanguine at gmail.

I'd definitely go the IDE route and either wire it to the iBooks IDE bus (not too hard if you don't mind butchering the iBook (not irreversibly either) a little; that, or if you've got money to burn, get a FireWire bridge.

The display in the 5500's is a standard VGA, but I'm not sure what the outputs are like; it connects to the onboard vid chip on the 5500 via that large adapter. I can check out what the connection comes down to further down the line though, without a problem. I'll look into it.
