; File: Hardware_Information
;
; Contains: This file contains information regarding hardware components used trought
; the source code. An explanation of each component name is given as well
; as the name of the CPUs which use the component. This is very useful for
; people new to ROM development. This is the place where you want to write
; all of those things you know about a particular chip. We need to know all
; of this things before you leave the project.
;
; Hint: If you want to know if a specific chip is used somwhere, look at the
; universal tables in UniversalTables.a
