I can't believe that I didn't get ANY responses my Tempest board
questions. Could anyone give me ANY information? I really would
appreciate it.
Thanks,

The program seems to be running, but I seem to be having problems in the
ALU / Pokey area of the Aux board.
Reason: Vectors jumbled on game grid and during much of the attract
mode. Sounds are random or just a bunch of noise. Controllers mostly
dead. Sometimes the buttons work (1/2 players, SuperZapper). Enemies
and player cursor look OK.
Question 1: Should rearranging the ALU chips produce different problems
on the screen or is it all one big matrix and that won't make a
difference? I tried cleaning / moving the chips around, but the results
are the same.
Question 2: Is there a chip / component that controls both Pokeys and
ALU?
Question 3: Has anyone seen these symptoms before?
Before you ask, Resoldered interboard connector pins (removed old
solder, replaced with new) on both boards.
Thanks for reading,
