JAMF, Damocles,
Thanks for your input.
I really don't think there would be anything to save in what is likely to be such a big step forward. It would be better to just pass it on to a member of the family and start from scratch.
Not including the more advanced control options, stick pedals etc., I would like to keep cost in the order of £500-600. Maybe this is not realistic in terms of ROF or the forthcoming SOW but I mean to get there eventually.
My current system is basically;
XP Home Ed
AGP Radeon 9600SE 128MB
Athlon XP 2800
1536 RAM Mem
When the laughter has subsided,

I would point out that all advice and recommendations will be gratefully received, built up and stored in a folder.
