RE: Blinking/fading Asteroids ......... monitor problem

Phil et Al,

I have exactly the same problem with my G05-801 ...

Mine also has another problem and I wonder if you could check yours to see
if it's just a single problem I'm chasing? If the ship is in the middle of
the screen pointing up and you fire a single shot, does the ship appear to
recoil (move about 3/4mm) when the shot leaves the top of the screen and
enters the bottom of the screen? Once the shot disappears the ship returns
to it's normal position. The same thing happens if pointing sideways and
firing a single shot but the ship "recoils" horizontally. This is
noticeable as a fidgeting ship during gameplay but less obviously!

Again, it's not the board - tried many and they're all fine in a cocktail
cabinet.

Cheers,

Steve

Subject: VECTOR: Blinking/fading Asteroids ......... monitor problem

Now here's something I haven't come across before and can't find any
references to - when playing Asteroids, when there are only a few asteroids
left on the screen (less than maybe four, even just one) sometimes the
brightness of a SMALL asteroid will 'blink' off for a few seconds, then
'blink' back on again. When I say the brightness blinks off, I mean that
the asteroid is still visible, it's just not as bright as it was.

It mostly (but not exclusively) only happens when an asteroid passes
through the lower right quadrant of the display.

It isn't noticeable when there are loads of asteroids on the screen, and if
one blinks/fades out then the rest are unaffected.

Now this is definitely a monitor fault (I have the G05-801) as it happens
with other Asteroids boards that I've also tried.

I suspect the deflection board, maybe even one of the output transistors.

I've checked Tom's excellent Black and White vector monitor FAQ but there's
nothing there that seems to be relevant, neither is there anything to be
found with a general web search.

Would anyone care to make any suggestions please?

Thanks,
Phil
