CPU advice

Hi,
Just purchased a second hand Mac G4.
taken the plunge and switched from PC for the first time.

Will be delivered in a couple of days

Its got 400Mhz CPU and wondered if it was easy to replace the cpu to a faster on i.e. 1gig.

Also its got 256Mb Memory.......is there two slots like in a PC...allowing you to add another 256Mb to it. If so what type of memory does it use.

Hope someone can help cheers guys

There were two different G4 towers that were rated at 400 mhz. They were code-named "Yikes" and "Sawtooth." Low End Mac is an invaluable site for info on older Macs: www.lowendmac.com. The info there will give you all the specifics for each model and also info about expanding or upgrading. The CPU upgrade page is: http://lowendmac.com/ppc/g4upgrades.html.
