You'll know then which components were impossible to source. Feel
free to fill us in on which ones they were.

As I've said more than once it wasn't a components problem. It's that
the boards were unmanufacturable at any affordable price. They needed
redesigning for modern components

I think Spud wants to know why they couldn't use the old boards with
the *old* components.

What old boards? They would have to be made and assembled from scratch,
an unaffordable prospect for the additional radios Railtrack wanted.

So we may be getting closer - the problem was a lack of boards, not a
lack of components to put on them?

Unmanufacturable covers a range of situations.

Nothing that was manufactered is unmanufacturable - it may not be
reasonably economic to do so, or in certain cases legislation may
prevent it (lead etc) but if it was built once, it could be built again.
