The vectors on my upright asteroids seem to have a 'bumpy' look to them when a graphic trvels over the screen. It's too subtle to pick up on camera.
The lines are sort of jagged and when I put the game in test mode, the cross hatch is 'bowed' rather than diagonal lines. The game runs just fine, just looks a bit crappy.
I recently pulled a deflection board from a friend's Asty and it cleared up all the problems on mine, so I KNOW it's just the deflection board problem.
I did a bit of comparing and the resistors at R621 and R721 on mine are the correct value at 6.8k ohm and his are both 3.3k - and his is better than mine - what the heck?
Also, some of the transistors on mine have been replaced in the past with bigger, upright transistors, rather than the lay down flat, held down with a nut type.
