i80

i80 is an Intel 8080 emulator with built-in CP/M emulation. It allows you to run programs written for CP/M 2.2 and lookalikes to run on a Unix machine. i80 provides a CPU, 64k of RAM, and a single I/O connection to stdin/stdout on IN/OUT 0.

WIP

i80 is very much a work-in-progress.

Short list of missing features:

• Incomplete AC flag handling (don't use DAA)
• Lots of CP/M BDOS routines
• Filesystem handling
• Bug-free experience
• Would be nice to emulate a Z80

You are welcome to implement any/all of these.

Notes on running

When running interactive programs, you probably want to run stty cbreak -echo before running i80 so that your terminal operates how CP/M expects. You can reset your terminal after the interactive program exits. There is no need to do this for non-interactive programs.
