Amazingly
there is nothing inside that 16pin DIL package. No silicon chip, no thick-film resistor
network, nothing. It is just a package with the pins.
Are you sure? They might have gotten a really good deal on house-marked Signetics 25120 chips, with not all of
the address lines
bonded out.
I've wondered why there wasn't a self-addressing serial version of the 25120, for
First In Never Out stores. That would fit in a 16 pin package I think.
