Just inquired about a G4 iMac offered on the local Freecycle list.
Here are the stats:
17 in. LCD display
800MHz processor (not intel, i forget what mac used before that,
but it's that)
80GB HDD
Apple SuperDrive (DVD-R/CD-RW)
nVidia GeForce4 MX series video
56K modem, 10/100 LAN
2xFireWire, 5xUSB, integrated Mic, space for AirPort Card (but no
card), mini-VGA out
includes Speakers, powercord, no mouse, no keyboard (both must be USB)
RUNNING OS 10.2 (but has disk for 9.something)
Not sure what model it is. Just that is is an 800MHz G4 CPU.
