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

A selection of [Paper Tape Images](/apps/pdp11/tapes/) have been archived for use by PDPjs machines:

PDPjs machines that contain a PC11 Tape Reader include:

The tape images are typically listed in a common configuration file that all machines can use, such as [demo.xml](demo.xml):

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

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:
