<The 148 and the 336 covers all variable speed microprocessors including a ring oscillator type. >

Where in the world do you see this?

IMHO the 336 covers a ring oscillator as the system clock. Period. Show me where it says anything to the contrary.

IMHO the 148 covers a ring oscillator as the system clock. Period. Show me where it says anything to the contrary.

If the above were not indeed fact, both the 336 and 148 would have been already found unpatentable. But you probably knew that when you started down this road.
