iAltair pretends to be a MITS Altair 8800 computer. It allows you to get the feeling of really old software such as the CP/M 2 operating system. The system is fully self contained and does not allow you to remotely add any code but you can try out Basic to run Eliza.
The Assembler
Learn Assembly programming and binary operations by creating pixel art. Each chapter introduces new operations, using 8-bit registers as your canvas to manipulate values and paint an 8x8 image. This app offers a fun, introductory approach to coding fundamentals.
- Learn Assembly programming
- Understand binary operations
- Create pixel art on registers
- Ten chapters with progressive learning
- Interactive 8x8 canvas
- Introduction to programming fundamentals

Learn Assembly programming and binary operations by painting little pixel art pieces. The app teaches different operations in each of the ten chapters. For each of the chapters you program an image with a limited set of commands. Eight rows of 8-Bit Registers turn into your canvas. Use Assembly to manipulate the values in every register, thus creating an 8x8 painting. 'The Assembler' was made as a small and fun introduction to Assembly, Programming and the Binary system that powers it all. The first version of this app was made for the Swift Student Challenge 2022 and won! I hope that you enjoy this project as much as I have.
