Thanks for the offers guys, I got the specific information I needed in order to get an accurate shipping quote :-). I purchased a lot of 18 Tektronix color graphics terminals (and one weird unknown-as-yet-to-me box identified as "PEP301 16MHz SYSTEM CONTROL"). The terminal models are 4105A, 9200T, and 9201T. As near as I can tell the 9200T and 9201T are color terminals configured for the logic 92xx series logic analyzer products. They may be 4105A's with just a different label/ROM or something, I'm not sure yet. I'm looking for manuals for these units: - 4105A Color Graphics Terminal - 9200T Color Terminal - 9201T Color Terminal - PEP301 16 MHz System Control The latter appears to be some sort of GPIB controller for test instruments. I suspect the 9200T/9201T manuals are buried in with the 92xx Logic Analyzer docs. -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>
