"EP'730 is the European counterpart of the basic MMP Portfolio application filed in 1989, which resulted in seven issued U.S. patents."

it should be clear that this patent encompasses more than the standalone 749 patent.

You were concerned about the ring oscillator. Here are claims 7 and 8 from the EP patent which support the validity of the ring oscillator and a separate clock.

7.The microprocessor of any preceding claim additionally comprising a ring oscillator variable speed system clock connected to said main central processing unit, said main central processing unit and said ring oscillator variable speed system clock being provided in a single integrated circuit.

8. The microprocessor of Claim 7 in which said memory controller incudes an input/output interface connected to exchange coupling control signals, addresses and data with said main central processing unit, said microprocessor additionally including a second clock independent of said ring oscillator variable speed system clock connected to said input/output interface.
