Pong Circuit-Level Simulation

This is amazing. The root page for it is here: <a href="https:&#x2F;&#x2F;www.falstad.com&#x2F;pong&#x2F;index.html" rel="nofollow">https:&#x2F;&#x2F;www.falstad.com&#x2F;pong&#x2F;index.html</a> and shows how each part works.<p>Though I don&#x27;t really understand how an image is produced on a CRT. In this circuit (<a href="https:&#x2F;&#x2F;www.falstad.com&#x2F;pong&#x2F;net.html" rel="nofollow">https:&#x2F;&#x2F;www.falstad.com&#x2F;pong&#x2F;net.html</a>), what is &quot;NET&quot; actually connected to?

Even more impressive is the analogue version without any ICs!<p><a href="https:&#x2F;&#x2F;www.eevblog.com&#x2F;forum&#x2F;projects&#x2F;oscilloscope-pong-for-1-or-2-players&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.eevblog.com&#x2F;forum&#x2F;projects&#x2F;oscilloscope-pong-for...</a>

I played one of the very first Pong coin-ops as some kind of a market test in the country at the then-new King of Prussia mall in the early 70s, just set out by a fountain. It didn&#x27;t generate much attention there but very soon afterwards the home versions and coinop CRT cabinets came out as &quot;video arcades&quot; started popping up all over. Culturally, there was a new market and suddenly something to do with your friends that didn&#x27;t exist before.

Pretty cool, although a digital circuit is overkill for pong...<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Tennis_for_Two" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Tennis_for_Two</a>

For those interested, there is a gate-level emulator for discrete logic arcades from the 70s: <a href="https:&#x2F;&#x2F;emulation.gametechwiki.com&#x2F;index.php&#x2F;DICE" rel="nofollow">https:&#x2F;&#x2F;emulation.gametechwiki.com&#x2F;index.php&#x2F;DICE</a><p>Unfortunately it isn&#x27;t actively maintained anymore.

Playing this, I found a weird bug where the ball oscillates between bottom and top of the screen. It happens when you hit the ball right at the top of the screen at a specific angle.<p>Screenshot: <a href="https:&#x2F;&#x2F;imgur.com&#x2F;m119hQH.png" rel="nofollow">https:&#x2F;&#x2F;imgur.com&#x2F;m119hQH.png</a>

Good old falstad.com. used his applets religiously throughout undergrad, many years ago.

When I was a kid, my dad had a book full of such maker models for doing special purpose game consoles.<p>So were the 70&#x27;s, build your own games console from the ground up.

Nitpick: this looks like a gate-level simulation, not circuit-level. Circuit level means transistors, resistors, ...

That&#x27;s pretty cool. I&#x27;ve seen that MAME has a netlist solver, so it should be able to play circuit-only games.

Wow! This is very cool

I love how this looks like neurons firing

omg this is so impressive, made me curious on what development approach did he do to create the website
