The other main Infocom interpreters on the Archimedes are Frank Lancaster's
Zip program and Edouard Poor's desktop interpreter (also called !Infocom.)
Zip is blindingly fast, and very compact, but runs outside the desktop using
the standard system font and plays only version 3 games.  The font size this
implies is enough to make it almost unusable on an A4.  Edouard Poor's
interpreter (at least early versions) runs in the desktop, but fails to
display a cursor and fails to handle backspacing properly.  Frank Lancaster
has also released ZipDebug, which is a combined debugger and interpreter; the
main point of interest is prototype support for version 6 games.

The only other Infocom interpreter I have seen on the Series3 is InfoPlay
ported by Oliver Wagner, and based on Mark Howell's ZIP interpreter rather
than the ITF interpreter.  Currently, InfoPlay suffers 3 main disadvantages;
it uses more memory (typically 6 to 10K, depending on the font loaded by
Infocom), it uses simple fixed-width fonts for output, and the OS integration
is slightly buggy; try ESCaping from a save dialogue, or killing the task
from the System screen.
