- 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 the Psion status
- window is 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 from before they will work.
-
- Version 1.7 generates much smaller save files than 1.6 and earlier;
- these cannot be loaded under 1.6. However 1.7 will read the older
- and larger save files.
-
- 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. 1.6s 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 InvisClues present
- 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, switch to a large
- font, quit and then try restarting. Fortunately, it is always
- possible to switch the font size as the abort message is
- displayed; the game should then work when restarted.
