MIT Clean-Room

The Cleanest NT Architecture on Earth.

An open-source, zero-telemetry, modern C++23 operating system executive built as a strict clean-room implementation. Resurrecting Dave Cutler’s 1988 DEC MICA & PRISM architecture for bare-metal modern computing.

MicaNT UEFI Boot Splash

Bare-Metal UEFI GOP Boot Splash

1988 DEC MICA / PRISM heritage tribute rendered via high-resolution 32-bpp linear framebuffer.

MicaNT ConHost Desktop

Interactive ConHost Win32 Desktop

Zero-telemetry executive running native commands, process scheduling, and real-time graphics.

"Cutler’s original design—the Object Manager, I/O Completion Ports (IOCP), Structured Exception Handling, and a clean hardware abstraction layer—was arguably the most advanced systems architecture of the late 20th century."
Dave Cutler • DEC PRISM & MICA Architecture (1988)

Uncompromised Systems Engineering

Built from the ground up in modern ISO C++23 with strict RAII, compile-time type safety, and zero legacy bloat.

⚡

Pure Object Manager (ob/)

Dave Cutler's clean handle-based namespace hierarchy (\Device, \DosDevices, \KernelObjects, \BaseNamedObjects) with type objects, handle tables, and atomic reference counting.

🛡️

Security Trinity (SAM, LSASS, Winlogon)

RFC 1320 MD4 NT-Hash generation, SAM user database, LSASS MSV1_0 authentication package with NTLM challenge/response, token synthesis, and secure desktop isolation.

🎮

PrismX & Prism3D Graphics

Clean-room DXGI presentation pipeline and Direct3D 11/12 execution engine. Features a built-in software reference rasterizer with Gouraud interpolation, depth testing, and WDDM kernel thunking.

💾

NTFS & FAT32 File Systems

Full 1024-byte MFT record parsing, runlist decompressor, B-Tree index traversal, FAT32 cluster chains, and Virtual File System (VFS) volume routing.

🌐

NDIS 6.x & TCP/IP Stack

Dual-stack IPv4/IPv6 networking, ARP resolution, ICMP echo, UDP datagrams, full RFC 793 11-state TCP state machine, and Winsock 2 (ws2_32.dll) userland bridge.

PrismX & Prism3D Graphics Subsystem

Named in tribute to Dave Cutler's 1988 DEC PRISM project. Complete clean-room graphics compatible with Microsoft's MIT-licensed DirectX-Headers and DirectXTK.

🖥️

PrismX Presentation Pipeline

DXGI-compatible presentation layer implementing IDXGIFactory1, IDXGIAdapter1, IDXGIOutput, and IDXGISwapChain. Supports 32-bpp BGRA double/triple buffering, FLIP_DISCARD presentation models, and direct blitting to the UEFI GOP linear framebuffer.

📐
