Reverse engineering is a great way to spend a day! :)
I've got a Planar EL panel on my desk, "liberated" from a supply of Sun
spares (apparently it's meant for a StorEdge A5000 series box). 160x80
pixels, and a 6x3 touchscreen. Very cool looking -- though interestingly
my camera picks it up as green, even though it's an amber display (looks
like a hybrid of a GRiD gas-plasma panel and an amber CRT). Natch.
Anyway, I think I spent about three days probing and tweaking it. It's a
standard controller (Epson SED1335) but the touch screen controller is
an ASIC. Turns out it's nice and simple though... Full details (pinouts
and code) on my website if anyone's interested.
