PC11 High-Speed Paper Tape Reader/Punch

PDPjs implements the PC11 component in pc11.js.

PDPjs machines that contain a PC11 Tape Reader include:

• Bootstrap Loader Demo
• PDP-11/20 BASIC Demo (with Debugger)

We have archived a selection of Paper Tape Images 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

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">
