Just got a G4 this evening. Yes it really old but always loved the look of these things! Looks like from a 50s sci-fi movie! So it was on guntree (for those who don't know it's like graigs list) The seller was glad to see back of it and had spent a while trying to sell it. It was cheap and did not haggle the price. So It is: 1GHz cpu. 80GB HDD 768MB ram (2100 266MHz) Has a pro keyboard and pro mouse but missing the pro speakers. No airport and no bluetooth either so will be looking to add them later. The aim is to use this machine for music playback in my workshop, once I cleared the workshop that is as right now cannot use it.
