  <DIV><BR></DIV>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>John
