I am finally putting my MH together...

I am seeing the screens below. I cannot get everything to line up properly. Is the the 1495 chips or the TL083?

Ignore the double lines (that's the scrolling)... check out the 5 in number of lives...

Oddly enough I have seen this on a Tempest. Turned out to be the damn edge connectors were weak on spring tension. Make sure they are seated good.
 
BIP was my first thought too...

Possibly dried out caps in the vector generator?

Know the history of the boardset?

What are your output voltages on the 7815 and 7915?
 
Quick update.

I tested this board at home with a 2nd 6100 and it looks the same. I took the board down to a friend's to test and it looks fine. I am going to test it in my tempest.

I am starting to think that its the power? I have not replaced big blue yet...

I replaced Big Blue... no change.

I will plug it into my tempest tonight (hopefully) and post some pictures.

I also noticed that when the screen scrolls right to left, it "squishes" or compresses on the side you are moving away from (you move left, the right compresses). Is that normal?
 
well after reading this thread it is 2 possibilties
1) monitor (which your going to check in your tempest)
2) bad edge connector (like dorket said)

my guess its still the monitor, but by me typing this it will prob be the edge connector lol

I have tried it with 2 6100s that I have. While the colors and convergence is bad on one, they both display the same thing... so I think that rules out the monitor...

Dok is coming over tomorrow... I will make him fix it... :D (I'm sure its his fault anyway... somehow...)

I think I have a spare tempest wiring harness... I will try that after I test in the tempest cab.
 
well if the edge connector is not properly touching the pads in the pcb
you could have diif probs all depends on which pins are not touching properly
for example if the pin for up is not touching at all then you cannot go up, but if it is touching but not properly then you will have up sometimes and sometimes not or not a fluent up.

now take that and apply it to any or all the pins, especially the power ones.

but i still would like to know if your 6100 are woking in the tempest cab.
 
It's part of my personal SOP to replace those edge connectors in all Atari vector games that I restore. They cost roughly $5 each, and are a bit tedious to do, but well worth it.

thanks. I will post more info when I try it...

Do you replace the pins too?
 
yes pins for sure they are what goes bad.
the cost of the actual plastic edge connector is minimal so while you have the pins out and changed just put it in the new plastic connector
 
Barry,

Have you connected the X-Out and Y-Out to your scope yet? That will eliminate a lot of the what-if scenarios here.

cool. I've done that before.

You know... I started to when the board did not start up, but once I got it running, I never went further... will try
