+description: >
+  Welcome to PCjs, home of the original IBM PC in a web browser.
+  PCjs provides a variety of computer emulators written in JavaScript, including PCx86 for x86-based machines
+  (up through the 80386), C1Pjs for the 6502-based Ohio Scientific Challenger 1P, PC8080 for 8080-based machines
+  such as Space Invaders and the DEC VT100 Terminal, and PDPjs with support for PDP-10 and PDP-11 machines.
+  PCjs also provides an archive of selected historical PC software, publications, and reference materials.

+As discussed in /modules/markout/lib/markout.js, our Node web server recognizes the following machine properties
+in the Front Matter of our Markdown documents, for compatibility with the Jekyll web server:
+
+    'id' (eg: ibm5150)
+    'name' (eg: "IBM PC (Model 5150) with Monochrome Display")
+    'type' (eg: c1p, pcx86, pc8080, pdp10, pdp11)
+    'debugger' (default: false)
+    'config' (default: machine.xml)
+    'template' (default: machine.xsl)
+    'debug' (default: false; true enables asserts and is much slower)
+    'uncompiled' (default: false; true is useful for debugging but slower)
+    'parms' (stringified object that collects additional machine properties listed below)
+
+Note that if you want BACKTRACK support enabled in a machine, both 'debugger' and 'uncompiled' must be true.
+Also note that while multiple machines ARE supported on a single page, there are some limitations; for example,
+loading two or more machines of the same 'type' but with different 'debug', 'uncompiled', or 'debugger' settings
+may not work as desired.
+
+The following optional machine properties will be added to the 'parms' property:
+
+    'autoMount' (eg: {"A":{"name":"OS/2 FOOTBALL (v7.68.17)","path":"/disks/pc/os2/misc/football/FOOTBALL-76817.json"}})
+    'autoPower' (eg: true)
+    'autoScript' (eg, type Keyboard "$date\r$time\r")
+    'autoStart' (eg: true)
+    'autoType' (eg: $date\r$time\r)
+    'drives' (eg: '[{name:"68Mb Hard Disk",type:4,path:"http://archive.pcjs.org/disks/pc/fixed/68mb/win95.json"}]')
+    'resume' (eg: 1)
+    'state' (eg: state.json)

+
+      The following approach worked well before we converted most of the code to ES6 classes.  Unfortunately, ES6 classes
+      don't coexist well with the conditional Node require() statements inside the individual scripts.  Since we were already
+      stripping all the Node-related code from the scripts to build monolithic scripts that we could feed into the Closure
+      Compiler, we have simply moved those monolithic scripts from the /tmp folder to the /versions folder, with "-uncompiled"
+      suffixes.  And since they are now checked in alongside the compiled files, there's the added benefit that we can always
+      reference them from source maps.
+
+      So, the following template code is no longer of any use, but we'll leave it here for historical reference.  Note that
+      our Node web server still serves up individual scripts, because it has the ability to strip all Node references from the
+      scripts before delivering them to the web browser.  But that's not really feasible in the Jekyll environment.

+Welcome to PCjs, home of [PCx86](/docs/pcx86/), the original IBM PC simulation that runs in your web browser.  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 emulator of the [IBM PC and PC-compatibles](/devices/pcx86/machine/)
+* [PC8080](/modules/pc8080/), an 8080 machine emulator (see [Space Invaders](/devices/pc8080/machine/invaders/) and the [VT100 Terminal](/devices/pc8080/machine/vt100/))
+* [C1Pjs](/docs/c1pjs/), an emulation of the 6502-based [Ohio Scientific Challenger 1P](/devices/c1p/)
+* [PDPjs](/docs/pdpjs/), a set of machine emulation modules supporting the DEC [PDP-10](/devices/pdp10/machine/) and [PDP-11](/devices/pdp11/machine/)
+
+All PCjs machine 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.
+
+Demos
+-----
+Some pre-configured machines are shown below, ready to run BASIC, DOS, Windows, OS/2, and other assorted 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/).
