We were buying 8085s and later, 80186s by at least Q500, so we should
have been prime candidates. Since our application data base was
pretty much all DG BASIC, it would have made life a lot simpler. But
try as I might, I never could get any followup from the Fairchild
I'm not aware of any retail or hobbyist boxes of the time that used
either the 9440 or the SBP9900, are you? Contrast that with a few
boxes constructed on the IM6100.
Of course, Bill Davidow would never have put his stamp of approval on
the use of anything but Intel silicon.
