 * I'm not certain if the challenge actually uses SysAD, since
 * it has separate address and data busses.  (big ones!) and
 * separate address and data bus ASICs.

 * 
 * The main set of buses in the Challenge and Onyx system architecture is the
 * Everest address and data buses, Ebus for short. The Ebus provides a 256-bit data
 * bus and a 40-bit address bus that can sustain a bandwidth of 1.2 GB per second.

Gaaahhh, you're right. It's been longer than I thought since I last
worked on a Challenge system. SysAD is the Origin bus, Ebus/Everest bus
is the Challenge bus.
