	But, since 5MHz operation effectively renders the cassette port unusable, a switchable design might also be nice.		But, since 5MHz operation effectively renders the cassette port unusable, a switchable design might also be nice.
	Switchable means that you can control the speed from BASIC.		Switchable means that you can control the speed from BASIC.


			== UPDATE Nov 2023 ==
			I've developed a really good solution that works for M100, T102, NEC, T200, M10 and KC-85.
