RK11 Disk Controller
|
|
--------------------
|
|
|
|
The RK11 Disk Controller controls up to eight RK05 disk drives, which in turn read/write [RK03](/disks/dec/rk03/)
|
|
disk cartridges.
|
|
|
|
RK03 disks are single-platter cartridges with 203 tracks per side, 12 sectors per track, and a sector size of 256 words
|
|
(512 bytes), for a total capacity of 2.38Mb (2,494,464 bytes).
|
|
|
|
Machines containing the [RK11 Component](/modules/pdp11/lib/rk11.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 [RK03 Disk Images](/disks/dec/rk03/) from [Paul Nankervis](http://skn.noip.me/pdp11/)
|
|
for use by those machines, which are listed in the following RK11 Device XML file:
|
|
|
|
- [Default](/devices/pdp11/rk11/default.xml)
|
|
|
|
which is typically referenced by a Machine XML file as:
|
|
|
|
```xml
|
|
<device ref="/devices/pdp11/rk11/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 RK11 device. For example:
|
|
|
|
```xml
|
|
<?xml version="1.0" encoding="UTF-8"?>
|
|
<device id="rk11" type="rk11" autoMount='{RK0:{path:"http://archive.pcjs.org/disks/dec/rk03/RK03-XXDP.json"}}' pos="left" width="35%" padLeft="8px" padBottom="8px">

<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/rk03/RK03-XXDP.json"/>
|
|

|
|
<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>
|
|
```
