The Memoranda of the Project MAC/LCS Computer Systems Research Group authored by or coauthored with Jerome H. Saltzer page contains many reports detailing various aspects of that project, including network topologies and protocols that ran on those networks. [1] Network Implementation Note #25 goes into a fair amount of detail, including a map. [2] Local Network Note #32 also includes a map. [3] Noel and Michael Greenwald can probably give more info.
