we did in &amp;quot;Digital Logic&amp;quot; when I was a student, were that you could
take &lt;i&gt;any&lt;/i&gt; problem, express it as a set of states and transforms, and
boil that down to an optimal netlist of discrete logic gates.&lt;p&gt;Of course, in the mid 80&amp;#x27;s that was a pedagogical tool to lead us
toward register machines and von Neumann architectures, but there were
still some old-skool EE hackers around who built things like guidance
systems for the Navy which were hybrid analogue&amp;#x2F;digital &amp;quot;computers&amp;quot;
totally without CPUs or code. Today we have FPGAs and high level tools
for building ASIC, but cheap microprocessors effectively swept aside
an entire &lt;i&gt;approach&lt;/i&gt;.&lt;p&gt;Maybe we missed something. Many small and well constrained problems in
IoT type applications might better be served by hard-configured
solutions. They would use less power, be immune to malicious network
hacking, not need &amp;#x27;firmware&amp;#x27; updates,</text><parent_chain><item><author>ajp11</author><text>In the year 1974, Practical Wireless, a UK magazine, published a design for a pong game that connects to a television, called PW Tele Tennis.&lt;p&gt;It uses sixty four NAND gates, twelve NE555 timers, two dozen diodes and some analog parts.&lt;p&gt;It&amp;#x27;s about the most basic version of the game.
