I picked up this display earlier today for $4, so I'm not expecting much from it... but if I could get it to work, it'd be pretty bitchin'.
What I've got so far is that there's a single 18x1 header on it for data and I've traced out the two pads that control the backlight.
There are three HD61105 controller ICs and 16 HD61104 collumn ICs onboard.

I've googled about and found some old forums where people have asked for any information, but recieved no reply, so I'll try my luck here.
