Actually, it'd be nice if someone was looking at ULA replacements for
the Acorn machines anyway - all the other parts can still be sourced
pretty easily, but it's presumably reasonably difficult to find a ULA
(particularly wihtout destroying another machine in the process)
Of course maybe all of this has already been done by someone!
