Yes ! Nice one ! That would be it ! It is the female port 24 pin centronics.
"Used for HPIB/GPIB applications: connecting computer and instrument, IEEE-488 standard. The Centronics 24 connector has 24-pins arranged in two rows one on top of the other. The top row has 24 pins and the lower row has 24 pins." One of the chips mentions GPIB I think, I wonder what was connected to it ? Google finds loads of interesting things : "A bus system for Test and Measurement applications Introduction The GPIB bus was invented by Hewlett Packard at the end of the 1960's. The intention was to create a reliable bus system especially designed for connecting computers and instruments. This networked system has all features that are required to create a measurement system. Remote control of instruments is one aspect of these features, but there are other more important features like data handshake for reliable operation and real-time response capability, only to name a few. History: The original bus system, designed by Hewlett Packard (today the Test & measurement's division's name is Agilent Technologies), was called HPIB, a short form for Hewlett Packard Interface Bus. Because of its success and proven reliability, in 1973 the HPIB bus became an american standard, introduced by the IEEE. Since then, the name has been GPIB, for General Purpose Interface Bus. The standard's number is IEEE488.1 . I have never heard of that kind of connector before, pity the hard drive in this SE appears to be dead, that may have given some clues as to it's original use.
