JavaScript Machines: PC Simulation in a Browser


Mon, Nov 19th, 2012 12:00 by capnasty NEWS

Although not particularly powerful, the JavaScript Machine simulation lets you run the original IBM PC inside your browser.

the simulation is fully functional on all modern browsers (that I've tested). It's booting the original IBM PC Model 5150 ROM BIOS (no modifications), and it's loading the original MDA/CGA fonts. This configuration gives you more control, allowing you to toggle any of the SW1/SW2 settings to change the memory configuration, the installed video card (MDA or CGA), and the number of diskette drives. There's also a built-in debugger with lots of DEBUG-like commands, only better. And you can create your own configuration by tweaking the underlying XML file. I'll eventually do a write-up explaining how to embed it on your own web page and what options are available. The process is very similar to embedding the C1Pjs simulation that I wrote earlier this year--the XML is just a little different.
