Yes it's screen 2, 640x200 (CGA) but thanks to the pixel aspect ratio it looks like 640x240
same as psion 5. So any image must be squeezed vertically to 80% to looks correct...
It uses Lxpic, and the screen should display 4 gray tones... alas only on low jpg resolution (machine is rather slow) and the preferred picture format is .pcx monochrome
Anyway, it's a nice hardware, as you can take it with you and have an IBM compatible in the pocket. Some use it for reading books, and that could be improved. There is mostly a "vertical Reader" with small fonts, but no horizontal reader with any kind of fonts.
It has 640 KB for DOS + pcmcia slot for usual CF flash cards.
This palmtop has also limited Internet possibilities, -SIR port.. The WWW browser was released for free and enables IrDA connection if i recall. This is not from great use...
PIM, data base, spread sheets are inbuilt in the ROM
