T'was brillig, and slithy ....

Don't try to use any memory cards that have ram beyond 640K or you'll be 
sorry!

Actually up to B8000 you will be safe, maybe. Depending on your clone.

If ram exists, or is enabled beyond 640K bytes, you run the risk of having
a buss contention problem between the ram and video memory, hence a system
crash or funnies.

I have a COMPAQ Deskpro and ran into that problem, but also tried a normal
portable variety COMPAQ and did not seem to have the problem. Confused?

Stick with 640K on an IBM clone to be safe.

BTW, I have used several of the AST cards in various computers at work, and
have not yet seen one fail or cause problems.  The problems I experienced
on my machine was with a Quadram board. I now have an AST board instead.

ta ta.
