I recently "helped" a friend by accepting a largeish box of discarded
engineering samples, etc., when his employer cleaned house. In the
box of assorted (and unsorted ;-) ICs were a quantity of 74170Fs (and
54170Fs. I have quite a few 54-series parts from places that spent
big bucks for protyping supplies then threw them out later), maybe 20-30.
Not recognizing the part number, I turned to the 'net to look them up. So
they are a "4x4 O.C. register file"... The only thing I could think to use
them for would be SSI/MSI microprocessor implementations. Did they have a
typical use?
One cool side effect of going through all these chips - most of them have
date codes from 1969 - 1978. Nice for repairing vintage machines with.
