I know there is amiga, atari st and possibly an early pc version but is there anything more sophisticated but along the same lines driving a stunt course?

I also used to enjoy stunt racer 2000 on the archimedes.

I'm more interested in the stunt course itself with ridiculous jumps and heights than racing other cars although not against that.

Well, that's a blast from the past.

What you're looking for is Trackmania Turbo!

Tons of crazy stunt tracks to master, 100 player online mode (you race against ghosts, still time trial basically), and there is a track editor to make your own.

No. But really cool.

Geoff Crammond. Loved his Grand Prix games on PC.

Thanks that does look like an excellent suggestion. I knew of the game had seen some videos but hadn't seen anything too exotic in tracks in the video but that definitely looks worth getting.
