-- Creation Date: 22:15:23 2010-06-30
-- Description:
-- Top level of the CPU proper, combining all the various modules
-- including Processor, Storage, Multiplexor and (eventually) Selector(s)
-- Page references like "5-01A" refer to the IBM Maintenance Diagram Manual (MDM)
-- for the 360/30 R25-5103-1
-- References like "02AE6" refer to coordinate "E6" on page "5-02A"
-- Logic references like "AB3D5" refer to card "D5" in board "B3" in gate "A"
-- Gate A is the main logic gate, B is the second (optional) logic gate,
-- C is the core storage and X is the CCROS unit
