RE: Asteroids/Asteroids Deluxe

Again, folks, thanks for all of your help. I managed to locate the short in
one of the boards (but the other two I cannot really make heads or tails).
The resistance value changes are so small, it is really tough to gauge
sometimes. I have a really nice fluke graphical multimeter, but it only
measures to 2 decimal places and I find only .01 changes in resistances in
the other boards and they don't seem consistent (ie. sometimes I probe a
particular section and get a value, and go back to that same row later, and
it has changed slightly, go back again and it is slightly different again...
very tough when changes are so minute).

Is the tool more sensitive to resistive changes (more than my $1500 Fluke
multimeter?) I may try the overload method.

Thanks Folks
Cheers
Andy

power the bitch up with a p.c. power-supply for 5 seconds, OR until
something goes bang/you smell burning.

then touch each i.c. until you burn your fingers.

this trick works great with defender pcb's when hunting bad ram chips!

the reason to use a p.c. supply is simple, they give out 18-35 amps!!!

if you use a game psu you will just blow fuses/damage the loom/psu.
