<DIV><FONT face=Arial size=2>Schematics would be great! My email address is
<A href="mailto:markhooks@earthlink.net">markhooks@earthlink.net</A>.
I'm speculating my unit is very early production. The serial
number ends in 5003 (perhaps the third one built?). I'm considering
modifying mine to be consistent with the schematics. It just doesn't seem
to have the connections needed to support the 6809E processor. The good
news is that all the parts are there to make it work. I just need to get
out the spool of jumper wire and make it happen.</FONT></DIV>

<DIV><FONT face=Arial size=2> My schematic shows s1-3 and s1-2 with one
side of each connected together and to the input pin 4 of AND gate U16. The
other side of S1-3 goes to the output side of the tri-state buffer U10 pin 8.
The other pin of S1-2 goes to the input side of the same buffer U10 pin
9.</FONT></DIV>

<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>

<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>
