You have the ISP jumper cable installed correctly?  Is the board set
properly to drive the clock input of the chip?  The 8515 is archaic and
needs an external clock (IIRC).  Is the ISP clock frequency less than 1/4
the CPU clock frequency?

   OK, perhaps I didn't explain my problem sufficiently.   I can neither 
read data from the on board 8515, nor write data to it (in either 
program mode or control mode. I cannot read the fuses or lock bits, for 
example, nor can I program or otherwise write to the device on the STK-500.

   When I try I get a failure dialogue box that includes a long winded 
"hint" to check the clock frequency on the processor being targetted.  
Since I can neither read nor write to the processor, how in hell do I do 
this?

  The Switches and LEDs demonstration program which comes burned into 
the 8515 runs just fine.


   So what am, I doing wrong? Nothing in the STK-500 User Guide has helped,

Tom
