Hmm, yes, if the card replaced the ramworks... ?
Great idea. Why just hold a copy of the aux ram when it can *be* the
aux ram ?
The memory was going to be there anyway.
And it does not complicate it, as it's only a matter of interfacing the
memory's OE or leaving it grounded, and the softswitches were being
monitored anyway.
What you do and how you do it with respect to the banks' contents is
another story.
Be it frame buffers or a ram disk...
Dealing with it is a pain, as it has always been.
The VGA card does not help in this respect, it's an Apple II after all.
Thanks for the idea, rich.
