Re: Lunar Lander help

After reading Commander Dave's LL back door sheet that describes the self
test procedure, I realized that I was running the test incorrectly. I had
powered up the game with the self test pin grounded, but the back door sheet
says to enable self test after the game has been powered up. If I run self
test after powering up the game, the full self test runs and I get the
indicated video display, just like what Dave Fish decribed. If I enable
self test prior to power up, the self test starts at the second stage, and
no video is displayed. I have no idea if that's normal or not, but that's
my story and I'm sticking to it. Fortunately, the game continues to behave
itself right now, but I can't rule out flaky 4016's. It will be interesting
to see how long it lasts in this condition before reverting back to the
defective state.

Thanks to each of you who provided feedback.
