LDA42

A computer with nothing hidden inside.

From the pixel on your TV down to a single CPU micro-step, everything can be seen, single-stepped and understood. The MAXIK console, the AGATA-1 processor, and a workshop where you write your own games.

Story

Why the console is named after our son and the CPU after our daughter — and what Comenius, the Amiga and the instruction LDA #42 have to do with it.

MAXIK

An FPGA console for your TV: the 8-bit AGATA-1 core at 25.2 MHz, games from an SD card, NES controllers, HDMI.

Library

Two books, thirty interactive lessons and coding challenges — from your first instruction to your own game.

Gallery

Boulder Dash, Manic Miner, Bomberman, Sopwith… games for MAXIK you can play right in the browser.

Workshop ↗

sap-3.com — editor, assembler and a time-travel debugger. This is where every game is born.

What makes this different

Fantasy consoles have no real hardware. CPU kits have no games. Courses have no fun. LDA42 has the whole chain: learn → write → debug in the browser → load into the console → play on the TV. The same binary runs identically in both worlds — and in both you can see what it is doing.
