With regards to ports 2B and 2C, they really are intended I think for 20 and 25 MHz operation.

You see, the SE was originally going to be 6/15/20/25 MHz. That is why port 20h will also accept 2 and 3 as values.

		+	I'm assuming that the only way we can achive 20 and 25 mhz is by physically modifing the calc. But I would perfer that as the naming scheme (plus note) then what I came up with. So I'd say yes.--[[User:Jim e\|Jim e]] 07:00, 23 Aug 2005 (PDT)
