Looks like the Wordpak manual has a schematic.  W00t!  Haven't looked to
closely, but based on the docs I've read, I think they're using the
6545, not the 6845.  The one nice feature of the 6545 was that it would
act as a gateway to the display RAM, requiring neither complex
multiplexing nor dual-ported RAM.

Of course, these days, dual-ported RAM is cheap, and any design I make
will probably use that..
