<DIV><FONT face=Arial size=2>Upon further examination it appears that dip
switches 2 and 3 (the ones that switch over from the 6809 versus
the 6809E) are not connected to anything. I wonder if there was a
re-design of the pod during production? My boards have a 1982 date on
them, revision B-1.</FONT></DIV>

<DIV><FONT face=Arial size=2>I've made some progress on this problem.
I've manage to track down a bad diode at CR1. I now get the input on
EXTAL through U22 as it should. I'm still getting the pod timeout
-attempting reset error though. It seems I'm not getting the E clock signal at
pin 34.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I've been comparing the schematics to my unit and
they don't match. Is there more than one schematic available? The one I
have is the October 1982 version. I hate working blind without
schematics.</FONT></DIV>

with a 6809 Pod Problem, 9010A</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>I'm at an impasse trying to fix my broken
6809 pod. I've scoured the techtoolslist archive and have not found a
solution. I'm getting the pod timeout -attempting reset error
message when using a 6809E processor. Here's what I know:
the pod works fine with a regular 6809, the dip switches are set right for
the 6809E, the 6809E processor I'm using works fine in a working star wars
board, the clock source at the input to U22 looks good on the scope,
the U22 enable line is high,but the u22 output is stuck low. Therefore,
there is no input on the processor EXTAL. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I think this is the problem. Where do I
go from here, replace U22? Before I go hacking around on a rare pod, I
want to make sure I'm on the right track.</FONT></DIV>
