Bootstrap Loader Demo (with Debugger)

This machine pre-loads the Bootstrap Loader code into RAM:

<ram id="ram" addr="0x0000" size="0x4000" file="/apps/pdp11/boot/bootstrap/BOOTSTRAP-16KB.json"/>

and then pre-attaches the Absolute Loader tape image to the PC11 Paper Tape Reader:

<device id="pc11" type="pc11" baudReceive="9600" autoMount='{path:"/apps/pdp11/tapes/DEC-11-L2PC-PO.json"}' ...>...</device>

Click "Run" to load the Absolute Loader. When the Bootstrap Loader is finished, it will HALT, leaving the Absolute Loader ready to run immediately after the HALT.

You can then select another tape image in the Absolute Loader format, such as BASIC (Single User), click "Attach" and then "Run".

If you need to start over, select "Bootstrap Loader (16Kb)" from the list of tapes and click "Load" instead of "Attach", re-installing the Bootstrap Loader directly into RAM.
