Pong on Oscilloscope

Look at the size of the breadboarded circuit!

Before watching I anticipated something really small. That's got to be the largest breadboarded circuit that I've seen.

 

[bassnut]

good grief, thats the way to learn, hardwired logic.

Haha! i want a breadboard that size.

Too bad they didn't go over a run through of the theory of operation...

Haha! i want a breadboard that size.

Breadboards are down to about $5 each. What's keeping ya !

Guess what i'm getting myself for xmas.

The very first pong games were done using opamps and timers. Two voltage ramps, a slow one for vertical and a faster one for horizontal were generated and these were used to generate all the timing signals. The pots for the bats were compared to the vertical ramp and the output triggered a timer to switch on the bat, this signal was anded with a fixed horizontal time to display the bat. The ball was two slower reversible ramps. Collision was done by anding the bat and ball signals.

I read a long article on this sometime in the early seventies and was in awe at the complexity of the circuits. Image my confusion when space invaders came out!! How on earth did they do that with opamps.

I found an interesting article that was probably written about the same time as I read about it. clicky.

I don't think they did?, Space Invaders was either logic chips, or may have been early microprocessor?.

I'm pretty sure (certain) that space invaders used a microprocessor but when I first saw it I was trying to work out how on earth they did it having just read the analogue pong article.

Things were changing so fast back then.

It did. Intel's 8080.

It did. Intel's 8080.

And now I can play it on-line with my Intel Core 2 Duo E7200 Wolfdale with 2gigs of ram. I still suck at it
