What you have just outlined is "EXACTLY".what was happening prior to this invention.

That is to say there was 'ONE' oscillator which controlled the timing of ALL functions of the computer,which included the I/O interface and the processing of the data. That single oscillator method limited the computer speed to the I/O capability..

What this invention did was to separate the I/O capability from the computational functions, by introducing a separate oscillator to control the processing of the data,independant from the I/O function. The problem that was solved by this invention was unique and was attempted by many others,without success..

This novel concept required another unique capability,,ie:, "Multi fetch,to increase the input speed, to the' Faster' CPU.. The I/O function was controlled by a separate oscillator of fixed frequency on a separate chip.. This is as simple as I can state it...A more detailed explanation can be obtained by reading the patent specifications..
