so i just bought a used ibook g3 800mhz 28 gb. very small i think right? anyway it took me forever to get into it i was locked out by username and password. I have gotten past that but would like to know what i should do to improve this mac. it is my first one and would like it to perform as well as it can. so what can i do? More memory, update software etc... how and where any help on this would be great i know i will love this ibook once i figure it out
