PC11 High-Speed Paper Tape Reader/Punch
---------------------------------------

PDPjs implements the PC11 component in [pc11.js](/modules/pdp11/lib/pc11.js). 

PDPjs machines that contain a PC11 Tape Reader include:

- [Bootstrap Loader Demo](/devices/pdp11/machine/1120/bootstrap/)
- [PDP-11/20 BASIC Demo](/devices/pdp11/machine/1120/basic/) (with [Debugger](/devices/pdp11/machine/1120/basic/debugger/))

We have archived a selection of [Paper Tape Images](/apps/pdp11/tapes/) for use by those machines.

To make it easy for PDPjs machines to load those tapes, we created the following High-Speed Paper Tape Reader (PC11)
Device XML file:

- [Default](/devices/pdp11/pc11/default.xml)

which is typically referenced by a Machine XML file as:

	<device ref="/devices/pdp11/pc11/default.xml"/>
		
Device XML files typically configure the device, list all the resource the device will use, and define UI elements
used to control the device, such as choosing which tape should be "attached" to the PC11 device.  For example:

	<?xml version="1.0" encoding="UTF-8"?>
	<device id="pc11" type="pc11" baudReceive="9600" autoMount='{path:"/apps/pdp11/tapes/absloader/DEC-11-L2PC-PO.json"}' pos="left" width="35%" padLeft="8px" padBottom="8px">
		<name>Paper Tape Controls</name>
		<control type="container">
			<control type="list" binding="listTapes">
				<tape id="tape00" name="Bootstrap Loader (16Kb)" path="/apps/pdp11/boot/bootstrap/BOOTSTRAP-16KB.json"/>

				<tape id="tape02" name="BASIC (Single User)" path="/apps/pdp11/tapes/basic/DEC-11-AJPB-PB.json"/>

		</control>
	</device>
