Hello all,
I recently purchased my first arcade cabinet. The unit was built in 1982 by Atari for Namco's Dig Dug, distributed in Canada by Dale Distributing Ltd. The original serial number for Dig Dug is 3243. Sometime in 1989 or '90 it was converted to Sega's Golden Axe.
It appears to have gone through numerous owners. The wiring is a nightmare, but after a bit of patience I was able to get it functioning (video, sound, controls all work). The Sega/JAMMA breakout adapter has been hacked to hell, the speaker is getting raw fully-amplified audio so it distorts quite badly. I can fix all this, I just want to make sure the game board is good.
I was able to get the game into the "test" mode and ran through all the self checks. All control inputs are working, all sounds are working, ect. The only issue I ran into was when it came to the memory test:
MEMORY TEST MENU
ROM TEST
-A7 Good
-A8 Good
-A5 Good
-A6 Good
FIX VIDEO RAM
-H15 Good
-H16 Good
SCROLL VIDEO RAM
-H13 Good
-J13 Good
COLOR RAM
-J9 Good
-J10 Bad
SCRATCH RAM
-E9 Good
-E10 Good
Now the monitor in this cabinet is the original one from Dig Dug. It has been rotated 90 degrees and is quite dim. It also suffers from some pretty nasty burn-in. "© 1982 ATARI INC" is permanently visible on the screen
. Because of this, I am not sure what effect (if any) the bad Color Ram has.
I wasn't able to find much information about the self test in the original installation manual from Sega.
Any help is appreciated!
