Marvin Minsky’s Marvelous Meat Machine
Thanks to hga [1], here is Marvin Minsky&#x27;s Universal Turing Machine emulator written in Teco.<p><pre><code>  MSG: APL    1

  APL is compact, I suppose.  So is TECO.  When I wrote the following
  Universal Turing Machine, which works, I actually understood it.

  iyyAyyAyy^[32&lt;i0^[&gt;ji110101110000010011011^[ 1uq&lt;htmbqq=&gt;

  I do not advise attempting to understand this code, which is
  almost as bad as that for the Universal Turing machine.
