I have a Midway 1978 upright Space Invaders. Purchased a Braze Kit & RAM tests fine but BIT FAIL. I have a cocktail board & replacing the original daughter board with cocktail board the graphics are fine but I have no sound
Replaced all 25S10 bit shifter chips, 74174 at C5-E5, 7417 F5, LM3900 at M4 & M5, 556 at H4, 7442 at E5, 74153 at A3 to D3 & all electrolytic caps, still no Invader Hit and square white block.
