It is linked= to in this thread where I will continue adding ESS-related materials (for = those interested in that sort of thing): http://www.classicrotaryphones.com/forum/index.php?topic=3D28001.0 The document therein is the Guide to Stored Program Control Switching, a Be= ll System document concerning #1 and #2 ESS telephone exchanges and varieti= es of networking connections. It's interesting in that the guide is three = separate little flip decks of cards, some of which can represent steps in a= network. Flip to the components you need and the traces at the edges meet= to create a diagram of that particular configuration. I quite like the co= ncept, seems like a great way to visualize variable networks. Anywho, as mentioned I'm going to be putting some more ESS stuff up there, = mostly related to 5ESS and 3B20 computers. That seems to now squarely be m= y main documentation focus since I'm starting to bleed the Bell System UNIX= well a bit dry of stuff I can randomly find on eBay. 5ESS and 3B20 are st= ill adjacent enough that I'm sure UNIX-y things will be scattered throughou= t this material. Finally, a long shot but is anyone aware of preserved copies (or in possess= ion of) the March 1980 issue of the Bell Laboratories Record? An index on = archive.org indicates that issue has a focus piece on the 3B20 which I am q= uite interested in getting eyes on. I've come across several other copies = around this time frame, some of which I've purchased to scan, but not this = one yet. As always happy to answer any questions about what I'm working on or consid= er scanning jobs for other documentation folks have leads on, happy new yea= r everyone! - Matt G.
