Subject: Re: VECTOR: 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.

I hooked up the 9010 ran
bus, ram, rom tests everything checks out fine.
But when I put the board into test mode with the pod
connected it doesn't bring up the test
screen.
Anyone had
this problem? Any ideas on what might be
happening?
Oh, also anyone know
a good source of turned pin sockets? I want to put sockets on the pods
to protect the pins.
