This started out really as an experiment to see if the BBC could in fact support two hard disc drives at the same time. I had never actually heard of anybody running two hard discs at once so I set about trying to put together my own Double Winchester Disc system. In fact, it was remarkably easy with the right parts.
The picture above shows that I have two hard drives, numbered 0 and 1, apparently providing me with over 84MB of space! This turned out to be rather an optimistic estimate as you will see later.
