	Of course it depends whether you have the ECS Agnus, but I digress.

	I believe it's known as 'slow-fast ram'. Basically it's just fast ram
that is slower than most fast ram. Personally, I call it a pain in the a*se!
Anyway, I believe the same thing occured on older 2000's as well (I have a
newer one, with all chip ram).

P.S. I believe there is a monitor for this group - could he make himself known
     please?
