Re: Lunar Lander Lamp drivers

I'm sure you checked for burned out bulbs... but I've never seen a LL that
didn't have at least 1 bad (loose) socket. The last one I worked on had 2
bad sockets. I just kinda bend them a little until the rivot is pulled
tight. I dont remember which lamps light up upon powerup, etc..and I
just played LL 2 days ago.. but it seems to me lamp 3 should not be on at
powerup. I have also had problems with the lights working from a dirty
edge connector on the main board.. if all the lamp
drivers/lamps/sockets/connectors check out just trace the lamp driver
lines in the harness into the first chip you find on the main board and
replace it.
