Hi Giovanni,
I'm afraid I don't have any other info on this disk.
I have looked at Neil's catalogue and, as you say, there is no mention of it in there.

I have the code numbers of most of my software on the computer but there is no code showing for that one.

The original disk should have a code on it but it's actually somewhere in my loft (not sure where) at the moment.
If I manage to find it, I will let you (and Neil) know what the code is.

Tony
