Rarely does a game from that era have that much complexity, and in CGA. Wow.

Also, an ASCII guide to gates:

         output  input(s)

                +
     NOT   --o< |--
                +

               -+--
     OR    --(  ( 
               -+--

               -+--
     NOR  --o(  ( 
               -+--

              --+--
     AND   --(  |
              --+--

              --+--
    NAND  --o(  |
              --+--

               - +--
     XOR   --(  (( 
               - +--

               - +--
    XNOR  --o(  (( 
               - +--

{C,P,N}MOS transistor implementations are exercises for the reader. :)


Apparently it's an Apple II game, not a CGA game. I was fooled too though.


Thanks. s/CGA/HGR{,2}/

Neat read (I never coded for Apple II):

Actually, they did port it to IBM PC and TRS-80 Color Computer.
