Configuration of the Master Series

Configuration guidelines for the Master Series
This section is taken from Support Group Application Note No. 203, Issue 1 dated 27th February 1992

After the Master series have had either their batteries or EEPROM replaced it will normally be necessary to perform some sort of re-configuration. This document describes all the configuration options available and what the default settings are when the computer is supplied by Acorn.

This only applies to the BBC Master 128, 512, ET and Compact models.

*CONFIGURE

On the master series, the configuration is managed with the *CONFIGURE command. This takes one or two parameters, the setting to set and an optional value for that setting.

Like other commands it can be shortened as *CONF.
Note the . at the end is required when using the shortened version.

General Information

The *CONFIGURE commands must always be followed by a CTRL BREAK to initialise the settings in the machine.

It is possible to use Edit supplied with the BBC Master to created a standard file which contains all the *CONFIGURE options which could be used to re configure the machine in one go by using the *EXEC command.

The Master Compact EEPROM has a limited life of 10,000 write operations. The chip is easily replaced when this limit is reached.

If ROMs appear in the ROM table as being unplugged it is possible to re - insert then using the command *INSERT followed by the ROM Socket number eg. *INSERT 13
