For archaeology's sake (and to contrast with X-Windows), here are a couple design [1] and protocol [2] documents RMS wrote about window system design, circa 1985, before X10R2 was released in 1986, but after all his work on the CADR Lisp Machine window system. (Not to be confused with Genera!!! [3])

There is a manual from Moon/Stallman/Weinreb: Lisp Machine Window System:

> CADR Lisp Machine window system. (Not to be confused with Genera!!!

Early Genera was based on the Lisp Machine window system. Later Symbolics introduced a new window system (Dynamic Windows), but the old one (TV, ...) was still provided.
