As a total aside, on some HP boards there is a 16 pin
DIL package with the part number 1260-0339.
Any ideas what that chip is?
What chip?
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.
The purpose of it? It's a connector (!) to fit one of those IC test clips on to
monitor various signals.
