I've received my email from Farnell and they've taken payment.
Apparently more will be shipping today so could have mine in the next
few days to a week if lucky.

Well done on getting yours so early Simon!  (and I was up at 6am on
the Farnell site)

Simon through on the Farnell website (just before 8am).  Perhaps enough people
Simon switched to trying phone orders when they opened that the
Simon website recovered very briefly?  It was pretty much inaccessible before 
and
Simon after that, as anyone that tried will remember!

 God knows how long it'll take before they start shipping RPs to general 
 customers though, after all the promo stuff with schools and
 such... how'd you get hold of one this early? :-D
 
 
 
 Quoting Simon Owen simon.o...@simcoupe.org:
 
 Seems like a promising start: http://simonowen.com/raspberrypi
 
 Speed is fine with the normal SDL build, even with demanding titles like 
 MNEMOdemo1 part 2.  It ran at about 450% with the
 emulator turbo button held (max speed but video capped at 5fps).
 
 The OpenGL version ran very slowly in X, as though it was missing hardware 
 acceleration.  That will be needed for the 5:4 aspect
 ratio feature, to make it look more like the original display.
 
 There wasn't any sound from the 3.5mm jack, and I did see some warnings 
 about not being able to find a sound device.  My monitor
 doesn't have speakers so I haven't checked whether there's anything over 
 HDMI, but I doubt it.  I'm using the latest Debian build from
 13th April, so I'll need to look into drivers etc.
 
 I had to head off to work so it's just a brief look for now...

 Versus running it on a normal computer, do we get genuine 50Hz output?

Setting an option in /boot/config.txt overrides the auto HDMI mode, so
it's be easy to force 50Hz (it'd be even better if it could selected on
demand at runtime).  Composite defaults to NTSC but can be configured as
PAL too.  I'll probably still need to implement some sound scaling to
keep it in sync with the vsynced video.

I'll also need to adapt the existing OpenGL code to use OpenGL ES for
hardware acceleration.  Regular OpenGL seems to be stuck in software
mode (glxgears gets just 16fps!).  The bundled GL ES demo ran perfectly
smoothly, of course.

On the sound side, the current ALSA driver is still very buggy.  Using
it gives a kernel 'oops' when anything tries to use it, so we might have
to wait a bit longer for that.

Just connect a SAMdac... hmmm usb version perhaps? ;-)
