Description by Jordan Ruderman (from the App Store)

OpenSol is an independently developed Intel 8080 computer emulator inspired by the Processor Technology Sol-20 Terminal Computer.

Explore a 64-by-16 character display, type directly into the original OpenSol firmware, and use the built-in Sol Command Monitor. Choose white, green, amber, or red phosphor; switch between a sharp flat display and period-inspired CRT effects; and use full-screen mode for an immersive terminal experience.

OpenSol includes:

• A complete independently written Intel 8080 interpreter
• Original OpenSol firmware and Sol Command Monitor
• iPhone, iPad, and Mac interfaces
• Direct typing, touch input, external keyboards, and compatible game controllers
• User-selected ENT and raw-binary file import
• Private on-device Recent Programs and session restoration
• Experimental virtual cassette and USB-audio cassette tools

OpenSol includes no SOLOS ROM, vintage applications, download catalog, advertising, analytics, tracking, accounts, or network service. Users provide their own lawfully obtained compatible files.
