Hi guys, I'm having issues where the screen is just black and white ( I changed the 555 timer and check the artifacing circuit). Now im also getting random characters on the screen.

 

Here's a video of what is happening

 

 

Any help would be appreciated.

Is that what the exhibit says? Because my generation (that grew up with the 2600) saw the space shuttle launches/landings in classrooms at school.

The poster on the wall had the shuttle so I assumed. I remember watching challenger in school, but thats about it.

Also did we ever figure out how much it would cost to make the shuttle today not inflation prices but part for part using todays replacement components? Im sure it would be a fraction of the cost.

What does that late 70's fake living room have to do with the moon or IBM?

They are showing how our generation saw the space shuttle.

[7800 White Screen question]

7800 gives me a white screen when I turn it on, I've checked voltages and there is +5v in the middle rail and most of the chips except Maria that is getting +8.1v and the 4013 which shows +4.98v. Are these values acceptable?
