For whoever wanted these. Here are some logic gates I drew up real quick.
They look a little better as vertical gates but are useable in the horizontal
form. You may want to look into the block characters of the ASCII character
set to make them look a little better. Here they are.

   74ls125 Tri-State Buffers

   For gates that need more inputs you could just use
                       __
   |_|_|_|_|_|  (or)     |
                       --|
                       __|  and the gate from above
                         |
                       --|
                       __|

   Let me know if these help and what you are using them for.
