Hi again.

From what I've read and been told, I made a mistake.

I have a Paradise EGA card that can emulate most of the common display
adapters.  I had played around with it in both EGA and CGA, the latter
referenceing the memory through $B800, and I NATURALLY assumed (Oy, the
WRONG thing to do with an IBM) that it was acessable from the full range
of $A000 to $BFFF.  I humbly ask to be forgiven for such actions.

:-)

I've been told that one can't create a 'blink' for EGA graphic modes, but
that you can flip between pages seamlessly, so how is this for a proposition:

What if you wrote your text character out to both pages, one normal, and
one reversed, and then hooked into the clock interrupt and at intervals
flipped the pages?

The only problem is that I don't have sufficent facilities (read in training
and Brains) to do it.  Anyone got a sugesstion?

thanx for all the help,
