For fun, I wrote a CHIP8 interpreter in Fortran recently [1].

Fortran is still heavily used in computational chemistry, computational fluid dynamics, marine engineering, nuclear engineering, reservoir engineering, and numerous other engineering fields. Volcanologists use it to predict ash dispersal [2]. Biomedical companies use it for cardiac electrophysiology. Econometrists use it to do tax research [4]. Plasma physicists use it to design magnetic confinement fusion devices [5]. Astrophysicists use it for relativistic magnetohydrodynamics [6]. NASA uses it for all kinds of fluid dynamics-related purposes [7] (read jet engines and rockets), and so do they at CERFACS [8]. For all I know, some integrated circuit manufacturers probably use it use it [9]. It's also used in ham radio and probably some military agencies [10]. It's used in vehicle crash testing [11]. It's used in combustion simulation software [12], fire dynamics [13], hydrometallurgy (ore leaching) [14]. US Geological Survey uses it for ground-water flow modelling [15]. We could go on and on.

What was the fun part ? CHIP8 or Fortran ? :-)

Both. :)
