iMac G4/1.25 20-Inch “FP” (USB 2.0)

The iMac G4/1.25 20-inch “FP” has its hardware housed in a hemisphere about 10 inches high, while the 20” flat panel TFT monitor tops it on an adjustable steel arm. Due to the largest screen in the line-up the base hemisphere is made a bit heavier to counterbalance it. The iMac 4G “FP” with 20” monitor shares the hardware with the iMac G4/1.25 15” features a 1680 x 1050 TFT display, a 1.25 GHz PowerPC 7445 (G4) processor with the AltiVec “Velocity Engine” vector processing unit, 256 MB of RAM (PC133 SDRAM), an 80.0 GB Ultra ATA/66 hard drive (7200 RPM), a tray-loading 4X “SuperDrive”, and NVIDIA GeForce FX 5200 Ultra graphics with 64 MB of DDR SDRAM (AGP 4X support). The fanless cooling is replaced with an internal fan. The internal speakers are swapped for the external optional ones. The model was available with Apple Keyboard and Apple Mouse.
