Right,
After much research, I have found that if I want to use FCP with this machine, I would need to use version 3:
System Requirements
OS Required Apple MacOS 9.2.2, Apple MacOS X 10.1.1 Min Processor Type PowerPC G3 - 300 MHz Min RAM Size 256 MB Min Hard Drive Space 40 MB Peripheral / Interface Devices CD-ROM
or 4:
System Requirements
Min Hard Drive Space: 1 GB
Min Processor Type: PowerPC G4 - 350 MHz
Min RAM Size: 384 MB
OS Required: Apple MacOS X 10.2.5
Peripheral / Interface Devices: AGP graphics card
or 'possibly'5.
Does anyone here have one of these that they might want to part with? If so, how much would you want for it. You can PM if you would like to discuss it. I'll go and have a look on Ebay in the meantime, although, I don't really trust Ebay. :-(
