Re: VECTOR: Missing Battlezone voltage and Germanium diodes

Thanks for the replies. I've replaced the regulators and two Germanium
diodes (NTE109 is apparently a sub for a 1N100, and the local electronics
shop had 3 in stock!), and now get the correct voltages at all the
testpoints on the A/R and the game boards. I've resoldered all the connector
pins, and looked with a magnifying glass for cold solder joints. But the
game still does not come up. The start button lights up steadily, not
blinking, and nothing happens when I press it. Any suggestion on next steps?
I have a logic probe and pulser that I've never used; can somebody point me
to a good website, or a good book, that could get me up and started on the
use of a logic probe on arcade games?
Thanks,
Lewis
