Virtual ][ is a program that emulates the vintage Apple ][ computer on your Macintosh. Virtual ][ lets you play the old Apple games, because it supports all graphics modes, lets you control the game paddles with a USB game pad or mouse and emulates the internal speaker. When you want to temporarily interrupt gameplay, Virtual ][ allows you to save the entire virtual machine, and continue later on from where you left off.

But Virtual ][ also supports more "serious" software, because it emulates many peripheral devices: floppy disk, hard disk, mouse, matrix printer, even cassette tape! It is also able to emulate the Z80A processor, allowing you to run the CP/M operating system.

Requirements:
OS X 10.11+
64-bit Intel
