92edcf0931 Transition to continuous assign, revealed equation problems.
But otherwise with problems fixed, simulation should be a lot faster.

56dd957402 Mac 128k PAL signals mostly working, hooray!
Also start working on BBU video timing signals, and documentation
improvements.

6678c4b2ab Commit BBU work-in-progress.
For comparative simulation, I'm also assembling the logic of the earlier
Macintosh 128K, and possibly also Macintosh Plus, in Verilog, and
planning on doing MLB board-level simulations too.
