I recently aquired a old Beige Mac G3 for really cheap $! The poor old 6 gig hard drive is dead tho the computer does at least have a screen open with a disc error "?" that keeps flashing as hard drive makes it's dying klunking sounds. The current drive is a Western Digital 64AA Enhanced IDE Hard drive. I have many hard drives lying aroung varying from 6 to 20 gig IDE's. Can I use any of these? Next ? What kind of memory does the old beige Mac G3 take / maximum memory? This one says on back 32MB but it has 2 of the 3 slots occupied by ram. Is this ram the same as PC 100 SDRAM? Finally I noticed it has a CPU that looks exactly like this one>>> http://www.cpu-collector.com/photos/XPC750ARX266PE_FL.jpg Can this old G3 be updated to a 500 MHz? like this card>>> http://cgi.ebay.com/Sonnet-Encore-G3-500mhz-ZIF-CPU-Upgrade_W0QQitemZ5809666407QQcategoryZ80031QQssPageNameZWDVWQQrdZ1QQcmdZViewItem The only info I can find about model of this mac is on front it says G3, Back says PowerPC G3 266MHz 512K Cache 32MB/6GB 24xCD/Zip/AV Model Number M4405 Thanks for any info as I am new to the Mac world! I have tried to lookup as much info on my own but still a little lost at this time. (Oh yea) do mac's have a bios? if so how would one enter it?
