I don't really have a clue ....

It's our age Jazz. You know how grandparents ramble on about their role in the second world war. We like to ramble on about the days when the NASA computer that put man(kind) on the moon was impressive, rather than something with rather less computing power than a common or garden laptop. Of course with a little more foresight we could have all overtaken Bill Gates years ago, we were just to busy doing other things while he made his zillions.

You just have to humour us a little.
