PDP-11 Boot Code

The project contains the following PDP-11 boot code images:

Boot code can be pre-loaded into any machine by including a <ram> component in the machine XML configuration file with the file attribute set to the filename of the image, along with optional load and exec addresses; eg:

<ram id="ram" addr="0x0000" size="0x4000" file="/apps/pdp11/boot/bootstrap/BOOTSTRAP-16KB.json" load="0x3FE4" exec="0x3FE4"/>

If no load address is specified, the <ram> component relies on the "load" property of the JSON-encoded RAM image; otherwise, the starting RAM address is used. If no exec address is specified, the CPU will begin execution at its usual reset address.
