Hi,
Does anybody know where DEC flipchips with a blue handle
were used for? I have one numbered 'B161'.
Thanks,
Ed

handle
were used for? I have one numbered 'B161'.
A few were used in the straight-8, LINC8, etc. but mostly I
think of them in connection with the PDP-10 and such. I'm
not sure what gear would use a B161, specifically.
My understanding of the blue handle series is that it is like
the red handle (Rxxx/Sxxx) series, but even faster yet than
the Sxxx.

They are a faster logic family, similar to that used in the
earlier system modules. R-series was a reduced-cost family
making extensive use of code-capacitor-diode gating to use
fewer transistors. There's a discussion of the evolution of
DEC's logic families in "Computer Engineering; A DEC View of
Hardware Systems Design" by Bell, McNamara, and Mudge.
