8086tiny: the Smallest, Free, Open-Source PC XT-Compatible Emulator


Thu, Jan 23rd, 2014 11:00 by capnasty NEWS

Written in C and just under 25k, 8086tiny is the world's smallest, portable and functional PC emulator that can run on pretty much anything.

Despite its size, 8086tiny provides a highly accurate 8086 CPU emulation, together with support for PC peripherals including XT-style keyboard, floppy/hard disk, clock, and Hercules graphics. 8086tiny is powerful enough to run software like AutoCAD, Windows 3.0, and legacy PC games.

8086tiny is highly portable and runs on practically any little endian machine, from simple 32-bit MCUs upwards. 8086tiny has successfully been deployed on 32-bit/64-bit Intel machines (Windows, Mac OS X and Linux), Nexus 4/ARM (Android), iPad 3 and iPhone 5S (iOS), and Raspberry Pi (Linux).

The philosophy of 8086tiny is to keep the code base as small as possible, and through the open source license encourage individual developers to tune and extend it as per their specific requirements, adding support, for example, for more complex instruction sets (e.g. Pentium) or peripherals (e.g. mouse).
