From your first instruction to your own game

Everything you need to learn to speak MAXIK's own language. Step by step, playfully, and for real — no simplified toy models, this is the actual machine.

Books

All free to download as PDF, no sign-up. You pay for hardware at most, never for the text.

SAP-3/16 — Reference Manual

The processor's technical reference: architecture, programming model, a dictionary of all 79 instructions and the peripherals — 193 pages. Its opcode tables, T-state counts and microcode listings are generated from the processor itself, so they cannot drift from it. Download PDF, English ↗ · Czech ↗

A Computer in Your Palm

A guide to the whole machine: 21 chapters and 5 appendices on how the CPU, memory, video, sound, disk and interrupts work — written for curious readers from primary school up, with examples you run in the browser as you read. Currently in Czech. Download PDF ↗

Arkanoid — a game, step by step

The second book builds one real game from an empty screen to bouncing, brick-breaking and sound — 79 pages, 11 milestones, each with a running intermediate result. At the end you have a game and know exactly why it works. Currently in Czech. Download PDF ↗

Instruction cheat sheet

The whole instruction set on one landscape A4 page — print it and keep it next to the keyboard. Download PDF ↗

Interactive lessons

Thirty lessons right in the workshop — from "light up your first character on screen" to subroutines, the stack and interrupts. Each lesson has a task, hints and automatic checking. In Czech and English.
