   No schematics, but it's a simple setup:

   6309/6809:

   Vcc to 5V

   Vss to GND

   HALT, MRDY, DMA, FIRQ,RESET, IRQ, NMI all pulled to Vcc via 10K
   resistors

   10uF cap from RESET to GROUND

   8MHz crystal on Xtal and Extal

   22pF caps from Xtal to GND and Extal to GND

     The unit is a Hitachi 6309C, and I tried both a crystal and I also
     tried to connect up a functioning 8MHz oscillator. No dice.
