IBM 360/30 in verilog

[Guy Sotomayor Jr]

POP = Principles of Operations.  It is the 360/370 *bible*.  It describes (in detail) how
the architecture works (including all instructions).  It specifies what are “architectural”
(ie can be counted on by all models) and what are “implementation” specific.

Changes to the POP were *very* restricted…that is, the architecture committee needed
a long and detailed justification for any change to the POP and most didn’t make it in.
