Gates discussed the design of the new machine with IBM continually, 
usually with Estridge.  He pointed out that the open architecture of the 
Apple computer had contributed immeasurably to its success.  Gates had 
reason to appreciate the openness since the Softcard, Microsoft's only 
hardware product, was a cornerstone of the corporation.  Since Estridge 
owned an Apple II, he was leaning toward an open architecture at the 
outset.  With Gates's encouragement, IBM defied its tradition of secret 
design specifications and turned its first personal computer into an 
open system.
