 A version of DOOM for the G series, written in Saturn machine code. The game is DOOM's first level (E1M1, Hangar), rebuilt from the original data with the real BSP tree and drawn in wireframe on the 131×64 screen. Each frame takes 1 to 3 seconds, so it plays as turn-based DOOM rather than an action game. The game includes the world (doors, lifts, stairs and the exit switch), enemies (zombies, sergeants and imps with simple AI, drawn as black silhouettes), weapons and items (a pistol with auto-aim, ammo and health pickups), a HUD (health and ammo at the bottom of the screen), sound (short beeps for shots, hits and doors; the E1M1 theme on the title screen), and extras (a GAME OVER screen with restart, and a cheat for invulnerability and infinite ammo). |

Structural analysis software that solves beams or columns in sections with any angle of inclination an any kind of forces, presents the equations and plots the diagrams of internal forces. Plots: The axial force, the shear force and the bending moment of any queried member of any structure, and gives their equations.
This is a helpful tool for Electrical Engineering students. It is for PID calculations and creating Bode diagrams. English and Dutch version. Just start with 'Plot'.
