super pacman

[span...@yahoo.com]

well i replaced to blown fuses today and the thing loaded great and
played great. just turn it back on a few minutes ago to play a game or
two and it came on with some screen that was upside down. looked kind
of like a test screen. said ram 1 and rom was blank. is this thing
trying to say that RAM 1 is bad??

i changed out the chip at 2E and nothing although i figured something
out.

you turn the game on and the test screen shows up, but its upside down
and the game is frozen.

if you turn the test switch on, turn the game on, the test screen
comes up, says everything is alright. well if you turn the test switch
back off the game will play perfectly.

any ideas what is going on??
