[inforoots] Open versus Closed Architecture

[Bill Selmeier]

I always found it curious that IBM with the exception of disks, tapes and 
some printers, managed to keep most of their internal architecture secret, 
ended up with the PC design that was so open and replicable by many 
outside the company.  While conversely Apple started with an open 
architecture on the Apple II and ended up with the rather closed 
architecture of the Macintosh.

With an early key development engineer in the IBM PC and the Lab Manager 
for Boca Raton at the time on this list, maybe we can get the IBM decision 
making clarified.
