I am writing a program that needs to look at the actual memory used by my
video controller.  Essentially, I would like to be able to look at the
memory and see the characters and attributes that are set.

I am using a EGA board running in CGA simulation and using TC 2.0.  
I tried a pointer and going through the memory and seeing what was there,
but I didn't happen along on anything that looked right.  I assume
that it is going to be somewhere above A000:0000, but I don't know where.

Anything would be helpful, so please post or email to me...

Thanx.
