	RX20 (un)support package for TOPS-10 7.03


    Contents, Installation Instructions, and General Cautions



RX20 (un)support allows TOPS-10 running on a KS20 (2020) system to (un)support
up to 2 RX211 floppy disk controllers, with up to 2 RX02 drives on each
controller.  The (un)support provided is that of a non-file-structured device.
Some preliminary utilities are provided which may read DOS (or KLDCP or
RXDP) and RT format floppys.  

Installation instructions:
__________________________

To install RX20 (un)support, you will require the Field Image TOPS-10 7.03
distribution.  
The following files from the customer (un)supported tape are required:

Monitor modules:
	UNSUP.FIL	- Adds new modules to assembly and LINK templates
	RX2SER.MAC	- Device service routine

Documentation:
	RX20.DOC	- Monitor Calls insert for RX20s
	RX20.INS	- This file

Actual installation is fairly straightforward.  Perform the following steps.
	1. Use the MUNGEN dialog (in MONGEN) to INCLUDE the RX20 questions.
	   Procede thru the HDWCNF dialog.
	2. Ensure that the files from the customer supported tape are in
	   your build area.  UNSUP.FIL will cause the distributed monitor
	   build procedure to assemble ALL of the KS unsupported modules.
	3. Finish building your monitor according to the 7.03 Software 
	   Installation guide.

Hardware Installation:
______________________

slots.
