+DEC PDP-11 Tape Images
+----------------------
 
 We have archived the following DEC PDP-11 Tapes:
 
-- [Absolute Loader](DEC-11-L2PC-PO.json)
-- [BASIC (Single User)](DEC-11-AJPB-PB.json)
+- [Absolute Loader](absloader/)
+- [BASIC (Single User)](basic/)
 
 To make it easy for PDPjs machines to load these tapes, we created the following High-Speed
 Paper Tape Reader (PC11) configurations:
 
 - [demo.xml](/devices/pdp11/pc11/demo.xml)
 
+which is typically instantiated by a Machine XML file using:
+
+	<device ref="/devices/pdp11/pc11/demo.xml"/>
+		
 These configuration files create UI controls that allow you to choose from a set of tapes that are automatically sent
 to the machine's PC11 device.

+DEC PDP-11 Absolute Loader
+--------------------------
+
+The Absolute Loader is a special tape image that must be loaded in order to load *other* tapes
+which use the Absolute Loader format.
+
+To see the Absolute Loader in action, try the [Bootstrap Loader Demo](/devices/pdp11/machine/1120/bootstrap/debugger/).
