<DIV><FONT face=Arial size=2>Couple quick suggestions (I have not looked at this
board yet):</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1) Are you able to Run UUT? I always try this to
make sure that my pod works in the board. That is just a safety
check.</FONT></DIV>
<DIV><FONT face=Arial size=2>2) Do you have a probe? With a probe you can
confirm that you've mapped the right address to the right chip. What you can do
is something (manual from the keypad) like: </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> SYNC ADDRESS</FONT></DIV>
<DIV><FONT face=Arial size=2> WRITE @ <suspected start
address></FONT></DIV>
<DIV><FONT face=Arial size=2> LOOP</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>and then you can probe the 2114 at the chip enable
pin to ensure that the chip you is indeed getting selected. In your case, I
don't think it is. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Also 2114s (for one hi/lo 2114 pair), the test
range will be something like 0000 - 03FF. </FONT></DIV>

on Fluke 9010A</DIV>
<DIV><BR></DIV>
<DIV>Hi guys !</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>I'm facing one problem that is driving me crazy !</DIV>
<DIV> </DIV>
<DIV>I have one 9010A with Z80QT Pod, I'm testing one known good Frogger (Sega
Gremlin) board. So far so good ! But "the problem is" : I have one 2114
sockted at position 50, and does not matter if I remove this IC or
replace with a damage one, it passes on both short and long RAM Test... I also
did the Quick Test and nope.</DIV>
<DIV> </DIV>
<DIV>I'm testing the following addresses:</DIV>
<DIV> </DIV>
<DIV>8000h-87FFh Passes OK</DIV>
<DIV>A800h-ABFFh Passes OK</DIV>
<DIV>AC00h-AFFFh Passes OK</DIV>
<DIV> </DIV>
<DIV>I think there is something wrong on addresses... but I don't know the
right ones... According to James's website the addresses are Okay, instead of
AC00h-AFFFh that is not listed on the website.</DIV>
<DIV> </DIV>
<DIV>Some of you guys can help me on that please ?</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>Thank you very much !</DIV>
<DIV> </DIV>
<DIV> </DIV>
