I also did a Self Test with the cab, since my sound appears to be working fine. According to page 7 of the Asteroids Cocktail Manual you are to hear a series of beeps. High beeps mean something passed, low beeps mean that item failed. When tested, I hear only one low beep, meaning it's failing on the first RAM I'm guessing?
I am confused though, because the manual states there are to be 6 RAM locations (D2, E2, M4, R4, N4, P4). Given my board...
D2 slot appears factory blank, no chips there, what do I do here? (see attached photo) <-- Low beep, guess I am failing here??
E2 is shared with F2 and has a big chip in there (guess that means the RAM is part of the ROM?)
*see edit below *
M4 no questions here
R4 no questions here
N4 no questions here
P4 no questions here
I'm attaching all RAM/ROM pictures along with the manual descriptions. Any suggestions??

EDIT: Upon further investigation of the PDF manual I have, the PARTS list shows RAM being in locations (L2, M2, M4, N4, P4, R4). This differs from the chart on the SELF TEST page, which appears to incorrectly identify D2 and E2 as Ram locations. Based on the PARTS list, all 6 chips are identical in that they share a common "UPD2114LC" code on the chip.
