Omega Race work in progress

I've been trying to bring this Omega Race back to life for the last
few months. The game currently passes the self test and will play,
although there seems to be a problem with the vectors on the Y axis.
The text is flattened, and on some screens the text will bounce up and
down. The ship vectors are misaligned. So far the TL081s, TL082s and
4016s have been replaced, as well as the DAC in the Y circuit. There
is -15v at the DACs and +15v at the TL081s and TL082s.

Video below which shows the issue(s). Any advice is appreciated. Thanks,

Carlos
