Fwd: Re: [GreenKeys] Western Electric / Bell Labs made a micro?

Steve, et all,

At Illinois Bell we evaluated a digital test system from AT&T that 
used dual processors of this type for redundancy and reliability.  It 
did not work out that way.  The system had to be re-booted five times 
a day on average.  We chose the Hekimian Labs REACT system instead, 
much to the disappointment of the AT&T sales team.  Since the same 
processors seemed to work very well in other applications, methinks 
AT&Ts "Digitest" was an example of rush to market, or "wine before 
its time."
