The computer terminal fractals are generated by a lindenmayer systems subroutine.

You can find a lot of info on lindenmayer systems here: http://paulbourke.net/fractals/lsys/

The version used by the Jurassic Park SNES game is a stripped down version of this.

What's used:
  F Move forward by line length drawing a line
  + Turn right by turning angle
  - Turn left by turning angle
  [ Push current drawing state onto stack
  ] Pop current drawing state from the stack

Sub routines exist, but not used by axioms.
  f Move forward by line length without drawing a line
  | Reverse direction (ie: turn by 180 degrees)

No code exist in ROM.
  # Increment the line width by line width increment
  ! Decrement the line width by line width increment
  @ Draw a dot with line width radius
  { Open a polygon
  } Close a polygon and fill it with fill colour
  > Multiply the line length by the line length scale factor
  < Divide the line length by the line length scale factor
  & Swap the meaning of + and -
  ( Decrement turning angle by turning angle increment
  ) Increment turning angle by turning angle increment

This is a video render I did of all 14 fractals: 

Here is an emulator I wrote for it. -It only contains the fractal data, NO ROM image:
