If I can remember back that far, there are some programming problems with
the CIO mostly with the manner of programming the link.  This may be related 
to the problem you see and I will have to spend a couple of hours with the
manual to try to remember the exact problem.  As I remember off the top of 
my head, care must be taken in programming the registers and setting the 
link.  As a rule of thumb, only handle one flag at a time and the last two
steps are to link the two and enable the count.  

Like I say, I can't remember all of the recommended proceedures.  If I can
remember more, I will let you know.  I may be able to get a hold of the
original designer of the chip.
