Barry Nelson tried to explain that cart to me but I still don't grasp the concept. He would be able to explain it.

Subject: [Coco] CoCo3: banking in ROM-Packs

I haven't found info about one point related to the
banking system in the, let's say, Super-Packs.
Reading Greg Zumwalt's article "Breaking the 32K"
I have found that writting a number (0-1-2-3) to
$ff40 will map to $c000 one ROM bank, good!
My question now is ...
What about the last 512 bytes ($ffe0-$ffff)?
Are they lost in every chunk of 16K?
Or, is there any trick to access all of these bytes too?

Thanks beforehand
