Star Wars

[DanP]

graphics during gameplay. Scale test

broken links/components on AVG board.

Symptom: Vectors are there but screwy

Action: Swapped in another known good AVG board

Fix: AVG board was bad, need to fix now...

Symptom: No TIE fighters. All other objects visible. When you reach the Death Star the game hangs.

Fix: Bad mathbox PROM @ 7K on the main PCB. Re-blowing a new PROM fixes the problem.

Symptom: First phase of the TIE fighters is OK. When you reach the Death Star the game pulses on and off causing the spot killer to kick in.

Fix: Bad address controller gat array @ 2J on the AVG board. Replacing the IC cured the problem.

Symptoms: Intermittent sound board resets during game play. Choppy / incorrect sounds.

Fix: +5dc voltage was +4.68dc at the AR 2 board. As a result around +4.5 was getting to the sound logic after wiring / interconnect drops. Adjusted AR 2 board to 5.10 to cover the drops. This allowed 5.05 at the chips. No more problem.
