I'm trying to look for one myself, but in a Ph.D program. It's maddening to me as it seems other people seem to know resources I don't. All others I asked said they either got paid by their parents (no starter for me there) or took out loans (another no-starter: I have undergraduate loans and paid for my masters so I wouldn't add to my debt.)
I'm sure there must be something for a scholarship for someone on the spectrum. A lot of people are overwhelmed by the social scene on campus and never finish school. There must be increasing awareness about this. My old school is now trying to make a program to accomodate people on the spectrum. Heck, even thinking about it, I wonder if my old school has scholarships for such people. You might want to check with your school as well.
