PDP-11/20 BASIC Demo (with Debugger)
------------------------------------

This machine pre-loads the [DEC PDP-11 BASIC](/apps/pdp11/tapes/basic/) tape image into 16Kb of RAM:

	<ram id="ram" addr="0x0000" size="0x4000" file="/apps/pdp11/tapes/basic/DEC-11-AJPB-PB.json"/>

You can also manually load it into memory using the [Bootstrap Loader](/apps/pdp11/boot/bootstrap/).
See the [Bootstrap Loader Demo (with Debugger)](/devices/pdp11/machine/1120/bootstrap/debugger/) for details.

There are also some [Debugging Notes](/apps/pdp11/tapes/basic/#debugging-notes) on the
[DEC PDP-11 BASIC](/apps/pdp11/tapes/basic/) page, if you're inclined to do some debugging with the built-in
PDPjs Debugger.
