DEC PDP-11 Bootstrap Loader
---------------------------
The blog post "[PDP-11 Paper Tape BASIC](http://www.avitech.com.au/ptb/ptb.html)" describes the *Bootstrap Loader*,
a small program used to load the *Absolute Loader*, which in turn loads the *PDP-11 BASIC Paper Tape*.
The **Bootstrap Loader** is a small program that loads the **[Absolute Loader](/apps/pdp11/tapes/absloader/)**,
which is then used to load other PDP-11 tapes, such as **[BASIC (Single User)](/apps/pdp11/tabes/basic/)**.
Here's what the *Bootstrap Loader* looks like:

DEC PDP-11 Tapes
----------------
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/).
