Acorn Risc PC Release note
• When a monitor type is configured using *Configure MonitorType,
many of the facilities of the Acorn Risc PC display selection
interface are not available. In particular the Display manager
window will not be able to present a list of available resolutions
and colours. However, you can still select the 'old-style' modes by
mode number from the icon bar menu.
Selecting modes by mode number
To select a screen display mode by mode number, use the Mode
entry on the Display manager menu. Clear the text in the writeable
field (you can use Ctrl-U to do this quickly) then type in the mode
number of the mode you want. Most monitors cannot display all the
numbered modes. If your monitor cannot display the mode selected
then an alternative mode with the same number of colours will be
chosen automatically.
Mode independence and monitors
As monitor technology has advanced, the ability to display some of
the older screen modes has been dropped. For example modes 16,
17 and 24 cannot be displayed on the AKF60.
Desktop icons change unexpectedly
If desktop icons change appearance unexpectedly, the cause is
probably an application which has redefined some of the desktop
sprites. You should upgrade to a newer version of the application.
Task Manager — resizing tasks and slots
You may notice when trying to resize a task or trying to set the Next
slot size from the Tasks window that you just can't select the amount of
memory you want. Do not worry. This is a side effect of the way the
Tasks window scales the mouse movement to enable computers with a
lot of memory to be usable. For small amounts in a slot you have
accurate control, but as the slot gets larger the changes in the amount
of memory get coarser and coarser. If this were not done then to drag
a slot of 32MBytes would require the mouse to be moved 3 metres!
