John,

If you have a normal system install you should have no problems with 
getting an image out of an 8500. 

The 8500 will enable the video output if it senses a connector when it 
boots up cold (not on a restart). Shut your machine down completely 
and then connect the video output Phono/RCA jack to your TV/VCR, then 
power-up the machine.

After the machine has booted check the 'Monitors & Sound' control 
panel and you should find that there are two monitors available. Pick 
your TV standard (UK is PAL), resolution and bit depth and then 
arrange the screens to your satisfaction. The video output will act 
just like a second monitor with a larger desktop, you can also show 
the same image as the main monitor (mirroring) but the image on both 
screens is restricted to the size of the TV resolution. To mirror the 
screens drag one icon onto the other, to un-mirror separate them by 
dragging.

If the machine doesn't output a video signal after power-up shut the 
machine down and have a poke under the hood (only if your up to it). 
Inside the case, under the power supply at the back there is a large 
horizontal card, that is the PPC processor card, immediately under 
that is a ribbon cable from the main motherboard to the back of the 
machine. Check that the connector is correctly inserted into the 
motherboard and then try powering up the machine again.

The size and depth of the images of both the video output and the main 
monitor are dependent on the amount of V-Ram you have in the machine, 
2mb or 4mb. When you start up the machine from cold it looks for a 
small signal leake on the video output and then divides the available 
V-Ram between the main screen and the video output. If you don't want 
video output, but want all your colours back on the main screen 
disconnect the video output lead from the machine and perform a 
shutdown, wait a few seconds, and the re-boot. The machine will then 
allocate all the available V-Ram to the main monitor.

Let me know how you get on or if you have any more questions.
