Murray, I have never been that good and probability, as with much of maths, has never been something that I am good at but I can relate to what you are saying. I had a Commadore 64 and used to enjoy the occasional challenge..

As for the newer computers and programming, I still have an old dos version of Turbo Pascal which I still like and use ocassionally. Number crunching wise, I have a Fortran Compiler which I believe is good but I haven't got round to learning the language and I probably would be incapable of taking advantage of its power as my maths is not good enough.
