This package is based on Infocom Task Force Interpreter, the sources for which are available by FTP from remus.rutgers.edu and ftp.cse.unsw.edu.au [149.171.16.16] in the /pub/infocom directory. Note that this contains only the original sources, and is almost certainly available from a closer FTP site. Formal Systems (Europe) Ltd made it possible to port the interpreter to the Psion by letting me use company compilers and equipment "out of hours." The bulk of the work on the original Psion version was done under software PC-emulation on an Acorn Archimedes. Later versions have benefitted from a Aleph1 PC card which has cut compilation times by a factor of four. Dominic Symes' incredible !Zap made editing the C source code much easier and faster. Paul Gardiner's lightweight wimp library made it possible to get early ports to the Acorn running much more quickly. DeskLib 2.03/2.04 made it possible to polish up the interface without driving Paul to distraction with feature requests. The quality of both the JPI TopSpeed compiler and Psion's Series3 libraries made it possible to shoehorn this application into the Series3. Mark Moxon allowed me to check compatibility with the Acorn Pocketbook. Finally, thanks must also go to the numerous members of the Oxford Archimedes User Group who first persuaded me to track down the ITF sources and suffered through my very early Acorn ports, beta-tested my early Psion ports at every opportunity (thanks Robin!) and finally complained enough about the existing interpreters to persuade me to port back to the Acorn. Graham Nelson's manual for Inform release 4 contains much useful background information on infocom interpreters and helped illuminate many corners of the original ITF sources. Similarly, Curses was useful both as another test file and as a fiendish distraction. The registration mechanism in 1.6 was inspired by that used in Steve Lichfield's Fairway application. The implementation is, however, totally different. For catching some of the glitches in early versions of 1.6, thanks go to Robin Watts (again) and Roger Burton-West.
