The new board, as it were (it's getting less new by the month) is Kip's
take on Searle's 6 IC 6809. His is 8, and offers some interesting
enhancement options.
But, when I try to bring the board up, I'm struggling:
* there is no signal on Q or E.
* Nothing of interest on the crystal pins (though my Tek could be
interfering with the feedback).
* I took the CPU off the board, breadboarded with HALT and RESET
high, crystal and caps installed, and still no Q or E. I tried a
known working 6809 from my SuperPET, and nothing.
I'm new to 6809/6309, so I am not sure where to start. I am sure once
I get the CPU running, the rest will be quick work, but the fact that I
can't seem to get a 6809 by itself to generate Q and E bothers me and
lowers my confidence that the board is ready to be debugged.
Kip, send the man a board. I'll buy it for him.
