The only difference between palm III and spt1500 is that the spt has a
barcode scanner integrated into it..

neither have i. :P

of course it is a simple job :P - in theory they should have the need
to only implement it in the "putpixel" routine - and seeing in done have
access to the source code for the roms, i cannot assume that :(
normally, optimizations remove these types of calls.. what happens if
putpixel is inlined? :P

yes.. a friend of mine once asked me about that.. (side controls)..
at the time, if i was to implement it, i would do the "screen drawing"
manually (using a back buffer).

ask 3com.. :P i heard rumors they dont really care about "games" on
the PalmOS - but my ears could be mistaken.
