Hey all, this is a longshot but... What I have is a DMD chip from an
infocus 4805 DLP projector. The array is 854x480 micromirrors using the
Darkchip II technology. What I want is a pinout for the back of the
chip so I can experiment with tilting the mirrors. A pinout for any DMD
might be a start...

Any suggestions of where to look for info would be great as well.
Thanks.

when you blow it up, start here, they have a few boardsets left from
working displays, this is where I got mine:

I spent a loong time a while ago looking for info on DMDs - detailed info is very hard to find.
I did however find a few projector schematics - do a web search for :
RD-JT30 Service Manual
RD-JT40 Service Manual
RD-JT50 Service Manual

I also found a manual for a Benq unit.

I can email the above manuals if interested, but be aware they are 2 to 7MB each

Hi, thanks for the offer, probably one manual would be sufficient?
Apparently my in box can store 1Gig.

Seen this link?
