The Mark 1 is a simulated early-1980s-era computer scripted in Linden Scripting Language (LSL), the server-side scripting language of Second Life. Developed by Northbridge Business Systems, it is the first computer capable of running user-supplied software written in LSL with full user interaction similar to home computers available in the early 1980s at a practical, realistic speed, synchronized live across Second Life viewers.
This website hosts official documentation on how to set up, use, and write code for the Mark 1.
Setting up your Mark 1 takes only a few minutes and requires only basic knowledge of how to move objects around in-world - no LSL required. The Quick Start page gets you up and running with SCOPE, the official operating system, on a Mark 1 with a keyboard and monitor.
The Guide to Operations is a complete manual on how to set up and use the Mark 1 and SCOPE.
The Technical Reference is a comprehensive resource for users looking to program software on the Mark 1 or looking for an in-depth look at the Mark 1's architecture.
