<DIV><FONT face=Arial size=2>So just because there is RAM hanging out there
doesn't mean that you can READ it back from the microprocessor and then the
9010A can not directly test it using the RAMTEST. BUT this doesn't mean
you cann't test it, easiest approach here is just write different patterns to
the VIDEO RAM & look at the screen. You probably could also use the
probe & collect signatures after writing a pattern to the RAM.</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>
