I'm stumped on this one. I've posted to get help with this problem I've never seen before. The asteroids are all half there.. the other half jumps around... I was told to put it in test mode.. and this is what I got..
I will say I have replaced All the DACs with known working. I've changed out the TL081's LF353P's, and CD4016's. With no change in picture.
Thanks for lookin!

Look at the vector timer circuit. I had something similar, where everything was really small..That turned out to the be vector scale circuit.
