Edward,

I send back your appl, with the necessary CHANGES.
This is working on my desk right now.

I have tested with 16mhz and 4mhz xtals, and it did it OK!
I also tested on different memory places and different bus velocities
successfully.

Please test this file as is, then look for the "vs." against your code.

Notice that I've used RADIX DEC to make work the formula.
A delay was added between set and get.


Regards,
Dennis.
