Apple iMac G4 700mHz M6498

The Apple iMac “700″ (Flat-Panel) is a new model iMac, replacing theiMac G4 5 inch Flat Panel G3 variant with the built in CRT. The internal components are housed in a gorgeous 10.5″ half-sphere, ice white case with a chromed stainless steel neck that supports a 15″ TFT Active Matrix LCD display. The iMac 700mHz “Flat-Panel”  ships with MacOS X (10.1) as the default operating system and Mac OS 9.2 installed, offering dual boot capability.

The iMac G4 700mHz ships with an ice white Apple Pro Keyboard and Mouse. Unlike some earlier iMac models that are convection-cooled, the iMac “Flat-Panel” series is cooled by a quiet internal fan. Please note that the case of the iMac “700″ (Flat-Panel) simply says “iMac” and the additional information is provided to distinguish this model from earlier ones.

Specs:

The Apple iMac G4 700mHz 15″ features a 700 MHz (G4) processor Apple iMac G4 Portsand a 256k on-chip level 2 cache, 128 MB or 256 MB of RAM (PC133 SDRAM), a 40.0 GB Ultra ATA hard drive (5400 RPM), either a tray-loading CD-RW drive or DVD-ROM/CD-RW Combo Drive, and NVIDIA GeForce2 MX graphics acceleration with 32 MB of DDR RAM.

Ports and Connectivity:

This system has three USB 1.1 ports (shared on two 12-Mbps controllers) and two Firewire “400″ ports (eight watts shared). Apple advertised that this computer had five USB 1.1 ports, counting three on the system and two on the keyboard.

Video and Graphics:

This model has a 15.0″ TFT active matrix display with a nativeTilt and Swivel Screen resolution of 1024×768 at “millions of colors”, driven by a Geforce 2MX GPU. It also supports “640 by 480 pixels and 800 by 600 pixels”. Apple reports a “typical” brightness of 200 cd/m, contrast ratio of 300:1, and viewing angle of 120 degrees horizontal and 90 degrees vertical.

Apple reports that this system has a “mini-VGA output port ([that] requires [a] VGA display adapter)” with support for video mirroring at output resolutions of “640 by 480 pixels at 60 Hz, 800 by 600 pixels at 75 Hz, and 1024 by 768 pixels at 75 Hz”.

Memory upgrades:

The iMac G4 models are unusual as they have two memoryiMac G4_memory port_undersideslots of different types — one on the bottom of the logicboard that is easy to access — and a second memory slot on the top of the logicboard that is difficult to access.

1. First  remove the “User Access Plate”, simply remove the 4 screws with the phillips screw driver. Photo below is with User Access Plate removed. Airport (802.11b) card and USER (sodimm) RAM slot.

2. Remove the base screws with a Torx-15. Then you can take off bottom housing. It’s a little bit tricky because there is a couple of connectors ( on the right side, connecting power and IDE to the motherboard),iMac G4 motherboard topwhen you look straight ahead onto your iMac) which fits pretty solid, but when you just pull strong enough on the bottom plate it loosens (but gently, please).

3) Replace internal PC133 dimm and re-assemble.
