How to Put Doom on A Calculator

Putting Doom on a calculator is a fun and creative project that combines retro gaming with modern technology. This guide will walk you through the process, from gathering materials to programming the calculator to play Doom.

Introduction

Doom is one of the most iconic first-person shooter games ever created. The original version was designed to run on limited hardware, making it a perfect candidate for retrofitting onto a calculator. By modifying a calculator to play Doom, you're essentially creating a portable gaming device that combines the simplicity of a calculator with the complexity of a classic video game.

This project requires some technical skills, including basic electronics knowledge and programming experience. However, with the right tools and guidance, anyone can successfully put Doom on a calculator.

Requirements

To put Doom on a calculator, you'll need the following materials and tools:

A calculator with a programmable interface (e.g., Texas Instruments TI-84 Plus CE)
A USB-to-serial adapter or a compatible cable
A computer with a serial port or USB adapter
Software for programming the calculator (e.g., TI-Connect CE)
Basic electronic components (e.g., buttons, LCD screen, microcontroller)
Soldering iron and solder
3D printer or access to a maker space for printing parts

Note: The exact requirements may vary depending on the type of calculator you're using. Always check the compatibility of your calculator with the Doom emulator before starting the project.

Step-by-Step Guide

Choose the Right Calculator: Select a calculator that supports programming and has a compatible interface for connecting to a computer.
Gather Materials: Collect all the necessary electronic components and tools listed in the requirements section.
Assemble the Hardware: Follow the instructions to assemble the calculator hardware, including the LCD screen, buttons, and microcontroller.
Program the Calculator: Use the appropriate software to program the calculator to run the Doom emulator.
Test the Setup: Connect the calculator to a computer and test the Doom emulator to ensure it's working correctly.
Enclose the Device: Design and print a case for the calculator to protect it and give it a professional appearance.

Formula

The process of putting Doom on a calculator involves several steps, each with its own set of calculations and considerations. The formula for success includes:

Success = (Hardware Compatibility + Programming Skills + Patience) / Time Required

This formula highlights the importance of choosing a compatible calculator, having the necessary programming skills, and being patient throughout the process. The time required will vary depending on your experience level and the complexity of the project.

Worked Example

Let's walk through a simple example of how to put Doom on a Texas Instruments TI-84 Plus CE calculator.

Connect the Calculator: Use a USB-to-serial adapter to connect the TI-84 Plus CE to your computer.
Install Software: Download and install TI-Connect CE on your computer.
Load the Emulator: Transfer the Doom emulator program to the calculator using TI-Connect CE.
Run the Emulator: Turn on the calculator and run the Doom emulator program.
Play Doom: Use the calculator's buttons to navigate the Doom game and start playing.

Tip: Make sure to back up your calculator's data before loading the Doom emulator to avoid any data loss.
