Unidentified chip -- Spoiler for HP 1260-0339

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.
