Don,
I see that Greg already answered, but I'll confirm it. The $C00000
memory placed in the A1000 by the Insider (II) was true FAST ram. There is
no contention with video.
The way the A2000/500 was designed is the only reason $C00000 memory is
known as half FAST ram. The reasoning I see was twofold. First, it was
cheaper since the Agnus could be used to control the memory. Second, doing
things that way allowed the memory to be converted to CHIP ram with an
Agnus upgrade.
