Bootstrap Loader Demo
|
|
---------------------
|
|
|
|
This machine pre-loads the **[Bootstrap Loader](/apps/pdp11/boot/bootstrap/)** code into 16Kb of RAM:
|
|
|
|
<ram id="ram" addr="0x0000" size="0x4000" file="/apps/pdp11/boot/bootstrap/BOOTSTRAP-16KB.json"/>
|
|
|
|
and then pre-attaches the **[Absolute Loader](/apps/pdp11/tapes/absloader/)** 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](/apps/pdp11/tapes/absloader/)**.
|
|
When the **[Bootstrap Loader](/apps/pdp11/boot/bootstrap/)** is finished, it will HALT,
|
|
leaving the **[Absolute Loader](/apps/pdp11/tapes/absloader/)** ready to run immediately after the HALT.
|
|
|
|
You can then select another tape image in the Absolute Loader format, such as **[BASIC (Single User)](/apps/pdp11/tapes/basic/)**,
|
|
click "Attach" and then "Run".
