Virtual AGC is a project providing emulators for the Apollo Guidance Computer (AGC), Abort Guidance System (AGS), and related peripherals like the DSKY, along with transcriptions of the original Apollo flight software source code. It also includes assemblers/compilers for the AGC so the historic software can be assembled and run on modern computers.

Use cases

• run the original Apollo 11 guidance computer code on a modern PC
• emulate the Apollo Guidance Computer and DSKY
• assemble AGC assembly-language source code
• study the Apollo flight software source code
• integrate an AGC emulator into a spaceflight simulator like Orbiter

When to choose

• you want to run or study authentic Apollo-era flight software
• you need an AGC/AGS/DSKY emulator for education or retrocomputing
• you're building a spaceflight simulation with historical guidance computers

When to avoid

• you need a general-purpose CPU emulator for modern architectures
• you want a polished turnkey Apollo mission simulator rather than component tools
• you need ITAR-restricted Shuttle or LVDC software in full
