Virtual Leo

The World's First Business Computer

Discover LEO I through a brand new interactive app

A critical piece of computing history in the palm of your hand

LEO I is a lost machine, in a lost room, in a lost building. Almost all evidence of it in the real world has gone. The Virtual LEO I app is a recreation of the room in which LEO was first built and operated.

Painstakingly recreated after several years of research, this is your chance to visit, explore & experience a world renowned piece of technology, and a chance to step inside the world as it was about to change.

A historic artefact, lost to time, digitally restored using historically accurate 3D Modelling

More than three years of work has gone into the research of LEO I and translating that information into highly detailed 3D models to represent as much of the original installation as possible.

Virtual LEO I lets you see LEO in its operational state and delve deeply into many of its parts to understand how it worked, what it did, and why.
