This is speculation mostly but the big square chip here, marked DIGIC, is possibly the processor. One of the other smaller chips near the corrosion might contain the firmware. http://www.pbase.com/gmr2048/image/69666958
These four large chips made by PSC are the DRAM chips, for the image buffer: http://www.pbase.com/gmr2048/image/69666954 The smaller silver rectangle is the 664MHz (or 64MHz, can't quite read it) crystal clock oscillator. The chip to the lower left? No idea. The metal plates are shielding against radio ferequency interference. Ahhhh, correction! The processor is here, not in the link above: http://www.pbase.com/gmr2048/image/69624861 It's the one on the left, a Toshiba MIPS based 32-bit RISC cpu, see: http://www.toshiba.com/taec/news/press_releases/2001/to-167.jsp The chip on the right is a Toshiba 8-bit single chip microcontroler: www.semicon.toshiba.co.jp/eng/solution/camera/07camera.html And about there I gave up looking through the photos. Blimey it's all so very mechanically complex!!! Eric. On 30/11/06, Shel Belinkoff <[EMAIL PROTECTED]> wrote: > For the most part, I don't know what I'm looking at. All those pics are > overwhelming.
