Hey all, been a while since I've been here, glad to be back! Anyway, this is a bit off topic to perl, but still related to programming in general; It's a question, but I didn't think it fit in the Seekers section (editors feel free to move it if you disagree). I am planning ahead on doing a mentorship project for next year. I want to do it on the prospect of using the negabinary number system in computer architecture, and how it would effect programming. Now, I have The Art of computer programming, and I got the idea from there (though sadly it is just a sentence, explaining the existance of such a number sytem only--in another book, it is merely a footnote). I have been looking all over the internet, and even in libraries, to no avail, thus I come here.

Do any of you have knowledge of this system? I have racked my head over it, but cannot figure out a boolean gate system of adding numbers together, if any of you know how to do this, I would be very apreciative. Also, in the Art Of Computer Programming, Knuth talks about a computer being built for use with the negabinary system, but doesn't develop anything from that; I was wondering if any of you knew where I could find information about that?

I know this is a lot to ask, but even just a point in the right direction would be helpful; I've exhasted all the means I know of (except for a few nasa-engineers that I know, that I plan to ask shortly), and I would appreciate just the mention of a place to look. Thanks all! P.S. For those who don't know, the negabinary system is almost like binary (base 2), but it is base -2. Thus, the 'columns' read 1,-2,4,-8,16,-32,64 ... instead of 1,2,4,8,16,32,64 ...
