OK, sounds like they have finally relaesed one. When I looked (at the

still deciding if we will release it'. Not the sort of attiitude that

I must admit that I am not overly in favour of

The docuemantion is attrocious. I couldn't find a schematic, or a real=20

Well, for all it's worth, there *is* a schematic...

The hardware documentation is basically in the form of a Wiki, which
I guess is how people handle documentation when they don't really
want to write documentation themselves (sometimes, it works; I'd
call the RPi Wiki a semi-success, because it's still really poorly
organized). There is a datasheet, though, that covers most of the
actual peripherals except for the video portion and a few others:
YEs, that's basicially what I was told. The video (in particualr the
accelerator) was not going to be documented withotu signing NDAs, etc.
Again, not something that (I would consider using.

As you've noted, it's somewhat redacted. To be honest, it's a lot
better than what I expected, given that it's a Broadcom part. We
have to deal with Broadcom parts at work from time to time, and
getting datasheets out of them is worse than pulling teeth. For
I can rememrbr when you just had to ask for a data sheet and it arrived
-- on paper -- the enxt day. No NDAs...
So yeah, while it's not *ideal*, it's a lot
more than I ever
expected the cyborg ultra-lawyers at Broadcom to approve.
That may be so, but it doesn't encourage me to buy the Rpi board...
