Re: burn in test opinions

Joe,

I don't do board repairs for others or sell parts, but when I do a major repair
I let the machine cook for at least 10-12 hours closed up before I declare it
operational and send it to the "coffee house" for operation.

I figure that it's better to do a test "in the environment" since there is less
cooling available in the closed cabinet with the PS working and the monitor
operating than if the board sat on a bench. Sometimes problems are noticable
only when the board reaches operational temperature and not in free air.

I got a Battlezone board set from Eldorado Games a few weeks back and it worked
fine outside the cabinet, but when closed up and running for a few hours it
decided to start displaying funky attraction screen graphics. Turned out one of
the PROMS on the AUX board unseated itself when the whole board got up to
operating temperature. No big deal - just reseated it, but just an example of a
problem (although minor) that occurs when operating in a closed environment.

    - Matt

P.S. - I was very satisfied with Eldorado - will probably buy from them in the
future. Anyone else have experiences with them?
