A couple observations:

1)  The 6702 has an input for the system reset. This means that the 6702 
must have one continuous sequence, OR, there is a software reset command 
for the 6702.

2)  A hardware chip of this size would have a response time of 50 
micrseconds, or less.  PEEKing and POKing from BASIC may not be fast 
enough to see all the output.

3) The 6702 is connected to phi2.  I may be capable of responding after a 
predetermined number of clock cycles, or of resetting if the correct 
sequence is not received in a predetermined interval.
