	The chip is made by Sanyo, with a resolution of 100 by 160
pixels, black and white. It uses a "bucket brigade" technology, which
scans the image out by shifting the rows down to an output shifter.

	I don't remember the number, but you should be able to find it out
from Sanyo. Incidently, Seiko Epson/SMOS make a _much_ better device, called
the HD7010. It is 244 x 244 pixels, and uses an interesting output scan
mechanism that avoids shifting the data across the screen (essentially, it
addresses each pixel directly).

	I don't have my data here at work (I do toy design indepently from
my _real_ job), but I will post what I have on _*cheap*_ video circuits
in a day or two. (I've looked into it several times in the past)
