RL11 Disk Controller
|
|
--------------------
|
|
|
|
The RL11 Disk Controller controls up to four RL01 or RL02 disk drives, which in turn read/write
|
|
[RL01K](/disks/dec/rl01k/) or [RL02K](/disks/dec/rl02k/) disk cartridges.
|
|
|
|
Machines containing the [RL11 Component](/modules/pdp11/lib/pc11.js) include:
|
|
|
|
- [PDP-11/70 with Front Panel](/devices/pdp11/machine/1170/panel/) (with [Debugger](/devices/pdp11/machine/1170/panel/debugger/))
|
|
- [PDP-11/70 with VT100 Terminal](/devices/pdp11/machine/1170/vt100/) (with [Debugger](/devices/pdp11/machine/1170/vt100/debugger/))
|
|
|
|
PCjs has archived a selection of [RL01K](/disks/dec/rl01k/) and [RL02K](/disks/dec/rl02k/) disk images
|
|
from [Paul Nankervis](http://skn.noip.me/pdp11/) for use by those machines, which are also listed in the
|
|
following RL11 Device XML file:
|
|
|
|
- [Default](/devices/pdp11/rl11/default.xml)
|
|
|
|
which is typically referenced by a Machine XML file as:
|
|
|
|
```xml
|
|
<device ref="/devices/pdp11/rl11/default.xml"/>
|
|
```
|
|
|
|
Device XML files not only configure a device, but also list all the resource the device will use, and define UI elements
|
|
used to control the device, such as choosing which disks should be "auto-mounted" by the RL11 device. For example:
|
|
|
|
```xml
|
|
<?xml version="1.0" encoding="UTF-8"?>
|
|
<device id="rl11" type="rl11" autoMount='{RL0:{path:"http://archive.pcjs.org/disks/dec/rl02k/RL02K-XXDP.json"}}' pos="left" width="35%" padLeft="8px" padBottom="8px">
|
|
<name>Disk Drive Controls</name>
|
|
<control type="container">
|
|
<control type="list" binding="listDrives"/>
|
|
<control type="list" binding="listDisks">
|
|
<disk id="disk01" name="XXDP+ Diagnostics" path="http://archive.pcjs.org/disks/dec/rl02k/RL02K-XXDP.json"/>
|
|
</control>
|
|
<control type="button" binding="loadDisk">Load</control>
|
|
<control type="button" binding="bootDisk">Boot</control>
|
|
<control type="description" binding="descDisk" padRight="8px"/>
|
|
<control type="file" binding="mountDisk"/>
|
|
</control>
|
|
</device>
|
|
```
