[Test-Equipment] seeking manuals of Analogic (Data Precision) Data 6000 Digital Signal Analyzer

[Glenn]

I've been searching for documentation on the Data 6000 series Waveform Analyzers (1982), by Analogic Corporation (Data Precision). 

These originally came with two manuals, I believe one for operating instruction, and the other a programming reference.

About all I have found online are a few ebay hits for the instrument itself (always without docs (: ) , and a good photo at http://forsale-l.amateur-radio-society.com/Electronics/Resistors/Analogic-data-precision-data-6000-dual-channel-analyzer/

As you can see from the front panel this is a "feature-rich" instrument. However, without access to the docs, I've only been able to play with some of the basic features. I'm particularly interested in its computer control interface and will need the API doc to write my control application.  I see four ports on the rear panel ( looks like GPIB as well as RS-232 :) 

This unit appears to be a keeper(not interested in selling), Its too bad that good surplus gear like this gets separated from its documentation :((

Does anyone know where the manuals for this might be obtained?
