Dave,

Perhaps one of your readers would know the answer to this.   I've  
tried various online and book searches and cannot find the answer.

Some time back, I read (somewhere) that Thomas Watson, Jr. took a big  
gamble in going from the IBM 700 series to the 7000 series by using  
all transistor logic.  This was circa 1959.   The figure I recall is  
that transistors were about $7 each (in 1959 dollars; about $60 each  
in today's dollars).

I'm looking for confirmation and/or a source citation for this.

Thanks in advance.
