Welcome to PCjs, home of [PCx86](/docs/pcx86/), the original IBM PC simulation written entirely JavaScript. It is
|
|
one of several JavaScript Machines in the [PCjs Project](https://github.com/jeffpar/pcjs), an open-source project that
|
|
includes:
|
|
|
|
* [PCx86](/docs/pcx86/), an x86-based IBM PC and PC-compatible emulator
|
|
* [PC8080](/modules/pc8080/), a 8080-based machine emulator (e.g., [Space Invaders](/devices/pc8080/machine/invaders/))
|
|
* [C1Pjs](/docs/c1pjs/), a 6502-based emulation of the Ohio Scientific [Challenger 1P](/devices/c1p/)
|
|
|
|
All PCjs computer simulations are written entirely in [JavaScript](/modules/). No Flash, Java or other plugins are
|
|
required. Supported browsers include modern versions of Chrome, Safari, Firefox, Internet Explorer (v9.0 and up), Edge,
|
|
and assorted mobile browsers.

The [JavaScript Machine](/devices/pcx86/machine/5150/mda/64kb/) above uses [PCx86](/docs/pcx86/) configured with an Intel
|
|
8088 running at 4.77Mhz, with 64Kb of RAM and an IBM Monochrome Display Adapter. For more control, there are also
|
|
[Control Panel](/devices/pcx86/machine/5150/mda/64kb/debugger/) and [Soft Keyboard](/devices/pcx86/machine/5150/mda/64kb/softkbd/)
|
|
configurations, featuring the built-in PCx86 Debugger. For even greater control, build your own PC. The
|
|
[PCx86 Documentation](/docs/pcx86/) will help you get started.
|
|
|
|
PCx86 has steadily evolved to support more classic x86-based machines, including the IBM PC XT, the 80286-based IBM PC AT,
|
|
and the 80386-based COMPAQ DeskPro 386. PCx86 fully supports the original machine ROMs, video cards, etc, and all
|
|
machines run at their original speeds.
|
|
|
|
The goals of the [PCjs Project](/docs/about/) are to create fast, full-featured simulations of classic
|
|
computer hardware, help people understand how these early machines worked, make it easy to experiment with different
|
|
machine configurations, and provide a platform for running and analyzing old computer software.

There are many more [PCx86 Demos](/devices/pcx86/machine/#ready-to-run-app-demos), including an
|
|
[IBM PC with Dual Displays](/devices/pcx86/machine/5150/dual/64kb/) demonstrating early multi-monitor support,
|
|
and multiple IBM PC XT machines running side-by-side with [CGA Displays](/devices/pcx86/machine/5160/cga/256kb/array/)
|
|
and [EGA Displays](/devices/pcx86/machine/5160/ega/640kb/array/).

C1Pjs

|
|
Below is the [OSI Challenger C1P](/docs/c1pjs/), another simulation in the PCjs Project.
|
|
It simulates Ohio Scientific's 6502-based microcomputer, released in 1978. More details about this simulation
|
|
and the original machine are available in the [C1Pjs Documentation](/docs/c1pjs/).
