Hardware, Embedded Systems It took the world a good while, but today, my Raspberry Pi finally landed on my doormat. Since it only arrived today, I haven't had the time to put it through its paces, but I do have a few first impressions to share with you all, while I also want to explain how the Pi will allow me to complete my already seven year long quest for The Elusive Three.

The main board for the RPi really is the size of a credit card, minus the rounded corners. At least, mine was when I checked it against one of my cards. Who knows, my own RPi may have grown since then. ;-)

HDMI isn't a hard requirement for video; the RPi also supports composite output, via the yellow RCA connector. Both of these are driven straight from the BCM2835 SoC. If you have an old Amiga monitor lying around somewhere, you can use that as well, if you don't mind interlacing in the scanning.

The Debian image uses the "armel" build, with software-emulated floating point. This probably accounts for some of the speed issue you're seeing. The Raspbian project is an attempt to provide a Debian-based system for the "armhf" architecture, using hardware floating-point instead.

The other part that's slowing down your video, is that the built-in VideoCore IV GPU requires firmware that isn't available under the GPL. The Raspberry Pi folks have expressed interest to Broadcom, to release the firmware without requiring an NDA-license. AFAICT, that's as far as it's gotten for now.

I wrote my own review here:
