- !!Speaker 1993 version
- -=-=-=-=-
-
- by Richard G. Hallas
- ____________________________________________________
-
- This is a very simple but useful program which is
- intended to be kept somewhere handy like the root
- directory of a hard disc. It provides a quick and
- easy control for the internal speaker(s). Simply
- double-click on the icon to toggle the state of
- the internal speaker between on and off. The
- state of the headphone socket will NOT change.
- Each time !!Speaker is run, the screen will be
- redrawn so that the icon displays the correct state
- of the speaker. The icon will also reflect the
- correct state when the directory viewer containing
- it is first opened, but since the program does not
- run continuously, there is no way to guarantee that
- the icon will always be correct, as other programs
- may alter the state of the speaker themselves. In
- order to make sure the icon is correct, simply run
- the application again. (It may be necessary to
- repeat this if you leave the speaker in the wrong
- state.)
-
- Notes
- -----
-
- In case of confusion, the application's icon is
- meant to be read as: "Turn speaker ON" and "Turn
- speaker OFF". These direct commands will be obeyed
- each time you run the application.
-
- This version of !!Speaker has been improved for
- users of RISC OS 3, and sprites are provided for
- multisync and hi-res mono modes. Users of RISC OS 2
- will simply not see these, but otherwise the program
- will work in exactly the same way on both operating
- systems. The correct sprites to use in any given
- situation are chosen by the (RISC OS 3) operating
- system.
-
- RISC OS 3 users can happily run !!Speaker from the
- Pinboard. It should also work from other sticky
- backdrop applications.
-
- Some of the newer Acorn RISC machines (such as the
- A3010) have internal speakers which are turned off
- automatically when headphones are plugged into the
- socket, and which turn on again when the headphones
- are removed. On such machines it is impossible to
- control the internal speaker independently of the
- headphones (the *SPEAKER command doesn't work), so
- this program is useless on such machines. Sorry.
