Aren’t there versions of this game and pong hidden in some of the newer digital scopes? I forget the brand, but I am sure that I read about it.

I just found the schematics for the original analog version:

Yea but without the mechanical relays, you don’t get the same tactile feedback as the original :(

I have so much more motivation to pick up a scope now.

#1: It’s a dual-trace scope, but you need two channels to get X-Y capability. Like other oscilloscope vector display projects, it’s not drawing the ball with a separate trace than the ground and the net. If you change the analog voltages fast enough, you don’t leave a visible line on the scope, at least when the intensity isn’t cranked up all the way.

wow took me a minuet to realise how they detached the ball from the rest of the trace so well... they didnt! its a dual trace scope lol.

no info on the original design. with digital accessible and easy to do i think a rebuild of the old 'analog computer' version would be much more interesting.

imo the scope clock is way better... http://dutchtronix.com/ScopeClock.htm
