On the other hand, the 4004 here is mostly the real deal:&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;jdryg&amp;#x2F;dls-schematics&amp;#x2F;tree&amp;#x2F;master&amp;#x2F;i4004&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;jdryg&amp;#x2F;dls-schematics&amp;#x2F;tree&amp;#x2F;master&amp;#x2F;i4004&lt;/a&gt;</text></comment>

In the game, little sparks&amp;#x2F;pulses would travel down wires, and there were various objects (primitive elements) that would manipulate the pulses (and gates, or gates, delays, relays, etc.)  If memory serves, each level had a set of pulses that needed to be generated to progress to the next level.  I have no idea what it was called and I&amp;#x27;ve looked for it occasionally without success.  Anyone know what I&amp;#x27;m talking about?</text></comment>
