ISTR hooking one up (after gaining access to some internal signals) with just composite video. I also seem to remember that, though quite crisp and bright, it has significantly less than 280 pixels within the 40-microsecond "window" of Apple II video, so you don't see all the pixels. It might be OK for graphics without fine structure, but for text it's a problem. -michael NadaNet networking for Apple II computers!

I looked at the pics of the IIGS screen on the PSOne LCD and it looked pretty good. Ever since the IIc first came out I've thought it needed a really good small LCD to make it a truly porrtable system and this looked to me like it might work. I knew there were people here who knew the technical aspects of the Apple II line better than I do, so that's why I threw the question out there.
The PSOne LCD has a very high quality display, but the problem is the overscan "protection" of Apple II video, which only uses 40 microseconds of the 63-microsecond horizontal period to display information. The border area is wasted, and with it, valuable LCD real estate. If fine detail and exact borders are not critical, then this LCD produces very colorful and sharp graphics displays from Apple video. Its picture quality is substantially better than most portable LCD TVs that I've seen. -michael NadaNet networking for Apple II computers!
