Quick setup
===========
Copy the INFOCOM.APP file into the \APP\ directory using one of
Psion's serial links and install using Psion-I in the usual way. The
same binary will run on both the Series3 and 3a.
Install any infocom data files in an \IDF\ directory, preferably on an
SSD, and make sure they have an .IDF extension.
Select a game-file from the system screen to start it running. If
there is insufficient memory available, the application will fail
silently. You will need somewhere between 60 and 80K of memory
available to start a game on the S3a depending upon the game (slightly
less on the S3 or for a second game running at the same time.) Memory
usage may increase slightly as you progress through the game.
To save and restore, either type the filenames in the usual way or use
the menu commands. The file selector expects that files will be
stored in the \SAV\ directory using a .SAV extension. The appropriate
file selector can also be pulled up by using the appropriate menu item
after the save/restore command has been typed. Saved positions are
usually between 1k and 5k in size, depending upon the game.
Since version 1.5, the Psion version has sprouted a Fairway style
registration system to get rid of the `nag' screens. This allows
users to disable the copyright messages, which otherwise appear on
save and restore operations, without having to reinstall the
interpreter.
The application attempts to fit in with the Series3/3a spirit as much
as possible, so all operations are available from the menu, the 3a
version zooms in the natural way and makes the Psion status window
available.
More details
============
If a save position is selected, rather than a game file, then the
appropriate game will be loaded and the restore done automatically.
The easiest way of making use of this is to construct an alias for
Infocom which lists the SAV files.
NOTE: The automatic restore will only work on positions saved from
1.6d or later copies of the interpreter. If you have any positions
you saved from earlier versions, these will need to be resaved before
they will work.
Note that version 1.7 introduced a new, smaller format for save files.
Saved positions from 1.6 and earlier could be read by 1.7, but cannot
be read by version 1.8.
Series3
=======
NOTE: This application has not been tested on a genuine S3. It seems
to work successfully in compatibility mode on a S3a and on the S3
emulator, but this is not definitive. 1.7+ will typically run games
in less memory than 1.4, despite the new features and the overhead
required to support the 3a.
The small screen size of the Series3 makes the built-in hints in some
of the later games almost unusable.
Series3a
========
Font switching causes problems on later (version 4 and 5) infocom
games, such as Sherlock and BorderZone. Basically these games read
the screen geometry when starting and ignore any changes, so the
status line is always drawn with a width appropriate for the initial
screen geometry. There seems to be no way around this problem short
of patching the original games. The game will still run, but the
status line may be not be fully visible in some font sizes. The
display preferences are saved between sessions, so you only need to
set them up once.
Some games refuse to start unless the screen is large enough. This can
be a problem if you start the game, zoom to a large font, quit and
then try restarting. Fortunately, it is always possible to switch the
font size while the abort message is displayed; the game should then
work when restarted.
The diamond key will toggle between the two fonts configured using the
Setup option. The intended use for this is when running games with
'quotes' like Trinity. Trinity requires that you have 60+ columns
when started, so it is necessary to have the main font be 8 point or
smaller. However it is then possible to flip to an alternate (and
more readable) font for the bulk of the game, flipping back to the
tiny font as required to read the quotes after they have been
displayed.
BeyondZork requires an 8 point or smaller font to be usable and this
must be selected as the game is started; zooming out at the initial
prompt tends to produce a display which only uses the left half of the
screen. The easiest way of doing this is to zoom out and then quit
and restart.
The "Tune memory use" menu option is available only when the
interpreter has been registered and allows you to trade off memory
consumption for performance. The first option controls the size of
the uncompressed page cache; increasing this will slightly reduce the
amount of time spent uncompressing modified pages. The second option
allows the backup bitmap to be enabled on the main window; this speeds
up redraw when removing dialogs at the cost of 10K of memory. The
final option enables undo support in the interpreter for those games
which can use it. Note that the undo is only available both if it is
turned on here and if the *game* supports it; if the game does not
then the memory needed for undo will not be allocated. The final line
of the dialog displays an estimate of the total memory used by Infocom
with the current settings. Note that none of the changes made in this
dialog will take effect until the interpreter is restarted.
