You imply that this only happens with programs that you write.  Is this true?
If so, what kind of programs are they?

Wait states may be your problem but there is another possibility perhaps
more likely.  Check in your setup to see if you can control your bus speed.
This is different from your CPU clock and is often stated in terms of a
divide factor of your clock.  If you are running the bus faster than 8 Mhz
try slowing it down to that.  Dividing the CPU clock by 3 should be close
enough.  The reason I think of this possibility is that you may be running
some particular device in your program that can't keep up with a fast bus.
That is why I asked what your programs are doing.  You may be having the
problem only when you go to a particular card.

Also try to run your programs on other people's systems to see if it only
happens on the one machine.  You say the dealer won't help you but he may
let you run your program on another machine of the same model.  If he won't
be sure to post locally the name of the dealer and the problems you are
having with them.  No sense someone else on the net getting stuck with
that type of "support."
