I will have to see. When we acquired the Aldrige collection at SMECC we pulled off all the really really early material and put the remainder in storage which should have some of this... we also have the unisys crossover stuff and when why bought up the Varian minicomputer too. I remember we boxed and boxed... and deep stored it. guess it did not seem "really old" at the time....but it has been about 10 years since we have pulled it out and run our hand through it. Background on Aldrige started on the electrodata Pasadena ... ended up running the phx field service effort here and was a great packrat. The effort to get to this material is a lot of work ed sharpe _www.smecc.org_ (http://www.smecc.org) In a message dated 9/4/2015 11:23:16 P.M.

We would be glad to hear from anyone who might have new material related to the Burroughs B6700. We're on the hunt for any manuals or software related to the Burroughs large systems so we can build an emulator for the B6700. This search includes the B5000, B6000, B7000 families, since there is considerable overlap across these families and collateral from one system family can assist understanding another. Example models include B5500, B5700, B6500, B7500, B6700, B7700, B6800, and B7800. We were amazingly lucky with the B5500 to have so much of the critical documentation (thanks Bitsavers!) and a complete suite of system software, but even though the B6700 was more recent and produced in larger numbers we're not having the same level of good fortune finding artifacts. What we have so far is documented here: https://docs.google.com/spreadsheets/d/1JnMsyE8ssJi_-MUsK0rT9LPtNpeJCpTv1QrF w-917Y8/edit?usp=sharing If you're interested in this system then you likely remember that it had a particularly impressive front-panel display, seen here: http://www.retrocomputingtasmania.com/home/projects/burroughs-b6700-mainfram e#TOC-B6700-Display-Panel This was known as the MDL display: Maintenance Diagnostics Logic display. Because the MDL had the 4 x top-of-stack registers down to the bit-level particular bit-patterns allowed words to be displayed. The early MCPs put IDLE into the display during IO waits, and subsequent releases: B for Burroughs, but sites quickly started putting their own company initials or the time. The Danish museum is so far the only place I've found that kept the MDL: http://datamuseum.dk/wiki/Genstand:11000045_Konsolpanel_Burroughs_B6700 Thanks to Finn Verner Nielsen for being so helpful and undertaking an expedition into their warehouse to locate and photograph the item for us. On that DDHF web-page you will see on the left of the picture the B7800 MDL they have too. My goal is to also construct a replica of the B6700 MDL. Steps undertaken so far: Posts to newsgroups Posts on LinkedIn, wikipedia, Yahoo groups Emails to a few dozen people who were involved with the system Trawling the Internet
