Teradyne PDP-11/84's

Hello, I'm looking at the possibility of purchasing an old DEC PDP 11/84 that was part of a Teradyne board test system. Does anyone remember seeing/working with these systems? In particular, I'd like to know: 1) Was it a common DEC PDP 11/84 with DEC markings, in a DEC rack, or was it redone by Teradyne, with their markings and special enclosure? 2) Were there any special firmware modifications that would make this difficult to use as a "regular" PDP 11/84? I'd like to obtain a 11/84 and a 11/34 for use at home for hobby purposes, running a mix of DEC and "other" operating systems, just for novelty. Sorry for the lack of experience in those questions, I've had very little experience with PDP 11's, but I do remember they were nice machines to work with when I did have the chance. Maybe soon I'll have all the time in the world to use one.... : ) - Matt "One World, One Web, One Program" - Microsoft Promotional Ad "Ein Volk, Ein Reich, Ein Fuhrer" - Adolf Hitler Many thanks for this tagline to a fellow RGVAC'er...
