TRS80 Emulator for Windows

This is a full-featured emulator of a TRS-80 Model III circa 1981. It includes:

• Complete and self contained with ROM and DOS built in
• Faithful Z-80 CPU emulation (including undocumented opcodes -- passes all ZEXALL opcode tests)
• Runs at standard 2.03MHz (or run up to 100MHz on a modern PC)
• Bundled disk and tape library includes applications, utilities, operating systems, and games
• Supports up to four virtual floppy drives, and all major virtual floppy formats (DMK, JV3, JV1)
• Tape drive emulation supports high and low speed reading and writing (CAS format)
• Windowed and full-screen modes
• Built-in Z-80 assembler and disassembler
• Real-time monitor of Z-80 CPU internals and IO device status
• Printer to file support
• Support for all video modes, including wide characters and Kanji mode

Project Objectives

• Run old TRS-80 programs for fun and general interest
• Document the internal workings of this ground-breaking 8-bit machine
• Provide examples of emulation techniques for others to use

To develop with this code, you'll need the latest MS Visual Studio 2017 (the free community edition works fine.) Create a Sharp80 project and sync to GitHub.
