Jamie Zawinski (jwz) has a port "Dali Clock" to PalmOS (with
sourcecode..) - - Maybe it could be useful to check that code out, if
for nothing else to perhaps get clues on compiling,  bindings, calls,
etc..(?)

Hope this wont get you on the wrong track, -I know it's not what you
really asked for.

  Hi,
 I have been dusting off some old Palm Pilots (III and V, mostly) and
 am running into "decayed link" syndrome on most of my searches.  I'm
 finding fragmentary web pages and links to abandoned projects from 7-8
 years ago, and only a few things that encompass what I'm working with.
  I joined the Palm Developers Network, but they don't make older SDK
 files available for download.  I'm really looking for the kit they
 used to have available that allows one to develop PalmOS 3.3-era stuff
 - so around 1999 or so, I think.  Does anyone on the list have
 something that sounds like that?  If so, please reply to me directly
 rather than clutter the list with stuff about Palms.
 To tie this search into recent events, I did see a few, very few,
 Palms at Dayton.  The best price I ran across was a Palm V w/cradle
 and wall wart for $10 (and another for $15 with box).  Unfortunately,
 that's more than they go for elsewhere.  I got home and ran across a
 Palm Vx at the nearby thrift for $6.99 w/cradle and wall wart (along
 with a Garmin 12 GPS for $1.91!)
 Since the DragonBall is essentially a dressed up MC68000, I've always
 appreciated the PalmPilot innards, but I've never had a need to build
 my own apps.  These days, everyone wants to support the Tungstens and
 Treos, etc., and have left monochrome Palms in the dust.
 Thanks for any assistance in locating ancient development tools.
