I have an A.P.B. "All Points Bulletin" Arcade machine that I am trying to fix.
Through many hrs and people I have figured out to be a Ram issue.
This is where I started -
I have an 'All Points Bulletin" or "A.P.B." . When I turn the game on it say - Quicktest , Ram 3, Bad - I have pulled out all the ram chips one by one and even intercharnged them and I still get the same message.
Note - there is 1 ram chip thats attached to the board non-removeable.
I have found the manual -
go to google and type - "all points bulletin" arcade manual - pick the 1st link , gives you the pdf file.
I have looked through this and it does not tell me which one is "Ram 3"
---------------------------------------------------------------------------------------
This is where I got to -
Get this....
I tried a bunch of different things all day.
I put back in the computer power supply that was in it double check connections
It comes up Ram 2 and 3 are "ok"
Puases on Ram1
So I think I found where Ram 1 is and there is 2 Ram chips in this spot.
I took out both and switch places and put them back in.
turned on machine and started up!!!!!!!!!!
Though when I went to start a game it froze.............
Maybe I just need to replace that Ram???????
-----------------------------------------------------------------
Now I am trying to find the Ram chips I need to replace though having a hard time.
I have listed them below.
Note - In the manual these are listed as "Ram" not "Static Ram"
If anyone can help thank you in advance.
