Need some help here.
A Jungler board made its way to me for repair from another member here, he can chime in if he wants too.
Board initially had no sound but came up and was playable otherwise. After I repaired the sound problems I unplugged the board and moved it to the side and started working on another one of his boards, a "600."
Got the "600" fixed and put the Jungler back on to test it (I like to make sure repairs are good before I box them back up) and now the game comes up but the graphics are a mess. Kinda like a PacMan board with the V-RAM addresser missing.
Anyway... Schematics are no where to be found so I'm looking at each IC's input and output to make sure they are working correctly. There are three chips on this board that I cant identify. They have the part numbers faded away due to age.
They are: 7L, 7E and 7A.
I know there are Jungler owners on this forum. PLEASE take a look at your board and reply with the part numbers on those IC's.
Please.
Thanks in advance.
