Author's notes: wherever you see "*" in a theme clue, read "Newton".
This bends the rules in a few places to get other words/letters to fit/cross,
mainly by poking a little fun at the Newton and its overly-maligned character recognition. So, there are several somewhat strange letter sequences in this puzzle -- notice '[misrecognized]' in clues.
xWord Buddy
It was possible once to download a .puz file on the Newton with Newt's Cape and
open it in Tactile's xWord Buddy (xWB) using a Newt's Cape helper app for xWB 1.x. Maybe version 1.0b9 that I found is too old? (plus it expires immediately: no unlock code avail).
xWB 2.1 has plugin settings for NetHopper & Newt's Cape, which don't appear to work
-- updating my helperApp page for xWB 2.1 doesn't work due to an apparent xWB API change
(before it also expired).
If anyone has a working Newton with a registered version of xWord Buddy,
and can transfer and display .puz files, could you send me a screenshot of newton1.puz? Thx. I'd then replace generic screenshot [on right]
CrozzWord
CrozzWord, a Java-based app that I developed in 2002-2003,
can still open local .puz files (Crozzword is no longer supported)
