Re: Using fluke 9010 on BZ in self test

I find that some games just 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.

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 & UWR).

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!).

As for sockets to protect the POD plug, I just use regular 40 pin sockets
as 'Sacrifice' pins.
