Click the screen or the button above to capture keyboard input. · Runs entirely in your browser — nothing is installed on your machine. · Type freely: it's a real DOS shell.
You're looking at a real cut-down FreeDOS machine running inside your browser via v86, a full x86 CPU emulator compiled in WebAssembly. The emulated machine has an RTL8029-compatible network card, connected via WebSocket to a relay server on x86.world infrastructure in Seattle, USA.
That relay bridges the emulated Ethernet frames into a real virtual network — complete with DHCP, DNS, and more. The in-browser DOS machine gets a real network IP address and can reach the internet just like any other machine on a LAN. mTCP NetDrive then connects to the x86.world disk archive over UDP and mounts a vintage disk image as a live drive letter.
No plugins. No downloads. No configuration. Just a browser tab, a virtual x86 CPU, and 40 years of computing history right at your fingertips before you even look to try on real vintage hardware.
After FreeDOS boots you'll see the x86.world welcome screen. Click the emulator to focus it, then press any key to begin connecting to the network.
Once connected you'll land at a DOS prompt on the mounted drive.
Type DIR to see what's there. Navigate with CD foldername or load the original menu with PCPLUS.BAT.
Find an .EXE or .COM and type its name.
Programs run directly from the network drive — no local copying needed.
Disconnect: A:\NETDRIVE DISCONNECT C:

Everything works: TYPE, COPY, MORE,
FIND, EDIT. A complete, real DOS environment.
This runs at browser speeds. On real hardware — a 486, a Pentium, even an 8088 — NetDrive flies, and programs run at the right speeds. Visit brutman.com/MTCP to set up your own machine.
