Does anyone know of actual Palm devices which use OS 3.5 and have Dragonball EZ based
graphics but which report that they can't get
4bpp mode?
This would be very useful information. (I'm not even aware of many OS 3.5 EZ gray
devices, except maybe the M100, M105. For
handspring, it seems that all their gray OS 3.5 devices are VZ based.
(On the same topic, do any of the VZ gray devices report that they can't go into 4-bit
mode via WinScreenMode?)
Thanks!
