I find that some games just&nbsp; won't work with the pod installed. It
appears that the pod loads down the circuit just enough to
fail...although it runs the tests just fine. Fluke does mention that in
UUTs with marginal design that the pod won't work right in the RUN
test.<br><br>
For example, I find in the Z80QT pod (Quick Test - late design) that
there is an added 1000pf capacitor on the output lines of the Interface
BCB that is not on the earlier designed Z80 or Z80/AA pods. It across A5
pins 17 and 15 (BWR &amp; UWR). <br><br>
You might want to check the update sheets for the pods, on the FTP site
(see below), these might help improve the POD response. I do need to
double check that all updates are there, and if anyone sees any missing
LMK or scan and email them to me or the INCOMING directory of
flippers.com (tell me they are there though!).<br><br>
As for sockets to protect the POD plug, I just use regular 40 pin sockets
as 'Sacrifice' pins. <br><br>
