- ModeInfo 1.01 (RISCWARE) -------------------------------
- This program is PUBLIC DOMAIN
- Version date : 17 Jul 1990 -------------------------------
-
- ----------------
- - Introduction -
- ----------------
-
- ModeInfo gives extensive information about screen modes, either standard OS
- modes or extra modes that may be available in modules.
-
- --------------
- - Info given -
- --------------
-
- The information given is mainly VIDC information, such as the values for all
- important registers and their meanings, and some miscellaneous other things.
- Most of the information is self-explanatory.
-
- VIDC register values are shown 'corrected', i.e. they reflect 'pixels' and
- 'rasters' as appropiate, as detailed in the VIDC data sheets. The control
- register (&E0) information is the (hex) value of its lower byte and this is
- further split up into the resulting values for the pixel rate, bits per pixel,
- etc..
-
- The horizontal and vertical scan frequencies and lengths of the horizontal
- and vertical sync pulses are calculated.
-
- All new modes in modules are based on OS modes. Wherever values for the new
- mode differ from the values for the base mode, the latter are shown behind
- the former in light grey. This makes it easy to examine what has been changed
- to construct the new mode. The value in light grey behind the mode number is
- the VIDC base mode (for non-OS modes).
-
- Unfortunately Acorn have put no SWI in RISCOS 2.00 to find out VIDC register
- settings for the standard OS modes. This forced me to search the OS ROM and
- use an obviously OS version dependant pointer to them. Therefore, this
- application does not currently work on any other OS than RISCOS 2.00.
-
- -------------------
- - The application -
- -------------------
-
- ModeInfo is a full RISCOS multitasking application, and will install itself
- on the iconbar when you double-click on the '!ModeInfo' application.
-
- The iconbar menu, popped up by clicking MENU on the iconbar icon, has the
- usual 'Info' and 'Quit' icons.
-
- By clicking with SELECT or ADJUST on the iconbar icon, the information window
- will pop up, and the current mode's information is shown.
-
- The 'Modes' icon gives access to a window in which all available modes are
- represented by icons. Icons for modes that are not currently available will
- be shaded. By clicking on a mode icon, the information window will be updated
- (or popped up) to show the selected mode's info.
-
- If modules with new modes are loaded after !ModeInfo (or if any modules are
- deleted/de-activated), the 'Modes' window will not correctly show the available
- modes. Simply click on the 'Modes' icon to re-scan them.
