   That would have been good, but bear in mind the original PC wasn't 
designed to be scalable at all.  The fact that the industry decided to 
adopt it as a de-facto standard was stupidity on the part of the 
industry, not IBM.  (not trying to defend IBM here, but this is just 
the way it is)

   I think they did a very good job for a cheap "throwaway" design done 
by junior engineers.  The production cost of the PC was almost nothing; 
there are exactly *zero* components on the original PC motherboard 
design that were more than a few dollars apiece.
