PCx86 ChipSet Component

Format

<chipset>...</chipset>

Purpose

Creates an instance of the ChipSet component, which includes support for the following hardware:

  • 8237 Direct Memory Access (DMA) Controller
  • 8259 Programmable Interrupt Controller (PIC)
  • 8253 Programmable Interval Timers (PIT)
  • 8255 Programmable Peripheral Interface (PPI)
  • Speaker (sound requires AudioContext support in the web browser)

Attributes

  • model (required)

    The IBM PC model number to simulate (must be 5150, 5160 or 5170).

  • sw1 (optional): A binary string representing DIP switches #1 through #8 for the SW1 switch block on the IBM PC motherboard, as follows:

    • #1:
      • 0 (OFF) for normal operation
      • 1 (ON) to loop in the ROM BIOS POST (Power-On Self-Test)
    • #2:
      • 0 (OFF) if math coprocessor installed
      • 1 (ON) if math coprocessor NOT installed
    • #3 and #4:
      • 11 for 64Kb
      • 01 for 128Kb
      • 10 for 192Kb
      • 00 for 256Kb
    • #5 and #6:
      • 11 for no monitor (or EGA installed)
      • 01 for Color Display (for use with CGA in 40x25 mode)
      • 10 for Color Display (for use with CGA in 80x25 mode)
      • 00 for Monochrome Display (or more than one Color/Monochrome monitor)
    • #7 and #8:
      • 11 for 1 diskette drive
      • 01 for 2 diskette drives
      • 10 for 3 diskette drives
      • 00 for 4 diskette drives

  • sw2 (optional)

    A binary string representing DIP switches 1-8 for the SW2 switch block on the IBM PC motherboard, indicating the number of 32Kb blocks of additional RAM installed (model 5150 only).

  • sound (optional)

    true (default) to enable sound, assuming the browser supports AudioContext, or false to disable sound.

  • scaleTimers (optional)

    false (default) to update timers in sync with CPU speed, true to scale timer updates to match real-world time.

  • floppies (optional)

    If no sw1 setting is provided, floppies may be used to specify an array of floppy drive capacities; eg, [360, 360] for two 360Kb drives; default is none. Valid values include: 360, 720, 1200, and 1440.

  • monitor (optional)

    If no sw1 setting is provided, monitor specifies the primary monitor type, and should be one of:

    • "none"
    • "tv"
    • "color"
    • "mono"
    • "ega"

  • dateRTC (optional)

    Allows a specific startup date and time (model 5170 only); the dateRTC string must be of the form:

     yyyy-mm-ddThh:mm:ss

  • Also supports the attributes of Component.

Bindings

  • sw1

    For use with a control of type switches, which creates a <div> that the ChipSet will use to display the current settings of the SW1 switch block.

  • sw2

    Same as above, but for the SW2 switch block, if any.

  • swdesc

    For use with a control of type descriptions, which creates a <div> that the ChipSet will use to display a text description of the selected DIP switch settings.

Example

<chipset id="chipset" model="5150" sw1="01000001" sw2="11110000"/>

Output

<div id="..." class="pc-chipset pc-component">
    <div class="pc-container">
        <div class="pcx86-chipset" data-value="id:'...',name:'...',model:'...',sw1:'...',sw2:'...'">
        </div>
    </div>
</div>

Also, if any controls are defined, another <div> of class="pc-controls" is created in the container <div>, with each control inside a <div> of class="pc-control".
