Screen Sharing with 10.4.11

I have been trying to share a 10.4.11 screen from a Snow leopard machine and have not been able to get it to work. Is it possible? If so is there DETAILED instruction of how do do it anywhere?

When looking at the other machine in Finder I see the sharing button but it won't connect for sharing (but can for file transfer)

My situation... I just got a 27" iMac running 10.6.2, but I still need to run some Classic Apps. I previously used a PowerMac G5 Running 10.4.11 which I passed onto another family member that still let me used Classic (which is why I did not upgrade it to 10.5)


I tried to get SheepShaver up on Running on my new iMac but only have a 9.1 Disk.

I have an older 800 MHz with 10.4.11 which can run classic.

Originally I had hoped to connect that to the video of the 27" iMac... But there are no adaptors and i read if and when they do exist they will be very expensive (this I did not know before I bought the imac)

Anyway one solution (outside of another monitor - not an option financially or space wise now) would be for me to be able to do screen sharing and control the PowerMac from the imac. That would let me use my classic Apps. I was thinking of connecting the machines via firewire 400 which I THINK should give reasonable performance (my router is only 100 Mbit)

Thanks
