Generally these old Macs only work with Apple style floppy drives, they use both a different cable and signaling standard than PC drives. If your drive isn't ejecting your best bet is to either replace it with a similar 1.44MB "SuperDrive", or service the drive. There are some good videos floating around the web about how to repair and maintain these old drives, and it isn't actually too hard to disassemble and clean them.

This teardown is 14 years old... You should be able to find the information you need by browsing through the other guides iFixit has for this machine, or looking around elsewhere on the internet.

Unfortunately not. The largest drive these machines support is 128GB total but you must partition the drive so that the OS / boot partition is 8GB or smaller. If you want the machine to be faster and more reliable, you can install a 120-128GB solid state drive with an IDE-to-SATA adapter.

Uggghhhh, Microsoft is still using X-Clamps. Didn't they learn anything from the original 360?

Could it really be? Just a little bit of user-serviceability?

Citation de Tom :

Yup, you're right. Didn't cross-check everything. Still wonder why the FCC version gets that chip and connector populated if they didn't put a cam on theirs. It could be just a debug port for non-production versions.

When they originally flash the firmware to the device, they have to put it in somewhere :)

ONYX might be the codename for the processor, or the codename of the GSM-based (AT&T) version of the phone.

Citation de Edis0n :

Except for the WiFi chip, all others are from 2007 (or before), so Apple had this going on for some time.

Probably not, these chips were most likelly used in older iPods, and provide legacy support (Since AAC Encoding hasn't changed much i the past 5-7 years) and the touch drivers were most likelly for the older iPods and iPhones, with slightly different instructions.

What interface does the drive use? SATA, or a proprietary connection?

Citation de Threedays :

No modchip now success. this machine will be a flop unless someone finds a means to mod it.

There really isn't much modding that can be done, it supports ripping games to the hard drive, it can browse the internet, the only reason I can see to mod it, would be to restore playability for PS2/PS1 games.
