Hi, Someone just gave me an old Tangerine G3 333 iMac. I already have a Powermac G5 and am thinking about setting this up in another room just for internet/email. It doesn't have the minimum ram right now to run OS X. If I upgrade it to 256K would it run OSX well enough to surf the net and do email? Also, when I opened the case I see what looks like 2 slots for memory. They aren't in the same place though. One slot is under a metal cage right next to a heat sink, and there is another off to the side. They aren't the same type of memory chips though. What is this? Thanks in advance for any help.
