Bought the G3 computer with keyboard for $20. Bought a VGA cable for $40, have a flatscreen TV with VGA input, and have a mouse. The computer works. Ethernet cable to wireless router, and Internet works.
One really shouldn't sell old computers because of the content, and listings of Internet activity history.
Now, is there a way of resetting everything? There is a password needed before I can update software, like safari.
