<HTML>Hi, quick update, well so far this is what i see. The handshake signals staus are: MAINSTAT toggling(pulsing) PODSTAT stuck high..(thanks adam) 
 
Also I've been checking the clocks...The E clock is held low at the processor...The self test socket seems to output the Q and E clock ok, but as soon as you plug the the CPU connector in the self test socket it holds the E clock low(same situation with any UUT) It's low on the input and output of A5 the custom interface(protection?) IC. A5 meters out ok.. 
 
BTW I'm running it with a 6809EP. 
 
Thanks again, Phil.

Clock is good on UUT of course?

typical, I went to use my 6809 pod last night and and have found it to be timing out in self test and with the UUT. I didn't blow it up, it worked when I last put it away and now it doesn't :o(. Anyone got any ideas/pointers, (IC specific would be good) on what to look at? I had a quick play last night and changed the leads, processor and the 6532 with no luck. I'm going to have another go today at it. 
 
Thanks, Phil.
