Hi.

I have different versions of my program, one for Colour devices, one for Greyscale ones and one for B&W. The only one I'm not sure about is the Greyscale. Which ROMs would support Greyscale so I can test my program?

Thanks.

OS3.1 support 2 bit grayscale, and OS3.3+ supports 4 bit grayscale.

It's also possible for older pre-OS3.1 dragonball EZ PDA's to do 2 & 4 bit grayscale, however there is no grayscale PalmOS API support before OS3.1, so you have to do direct CPU register writes... which is quite messy.

Yeh.. well I found the Palm IIIx is a greyscale device, so I used that ROM.
I didn't want to test greyscale on a colour device. Just greyscale on a greyscale device :)
