I take on board what you say about mounting the capacitors close to the chip but please could you tell me what TYPE of capacitor I need. It doesn't show them as electrolytic, so what type would you recommend that I order. Sorry to be so dim.

The 1uF's should be film caps (greencaps) - polyester is fine for this application.

If you wanted to get it going in a hurry, Tantalum's would work fine too, but not quite as well.

Many thanks for your information, it's very nice of you guys to help me out and answer my questions.

Agreed on the film caps but I would try to stay away from tantalums. They don't often fail but when they do, the magic smoke comes out - sometimes quite violently.

Indeed - I sorta forgot to add my "for prototype purposes only" disclaimer. I'd never use a tantalum in something I wanted to keep.
