DEC PDP-11/20 with BASIC and Debugger

The machine below pre-loads the DEC PDP-11 BASIC tape image into 16Kb of RAM:

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

You can also manually load it into memory using the Bootstrap Loader. See the DEC PDP-11/20 with Bootstrap Loader and Debugger for details.

There are also some Debugging Notes on the DEC PDP-11 BASIC page, if you’re inclined to do some debugging with the built-in PDPjs Debugger.
