Re: Debian Hard Float (armhf) for RPi

Given the requirements, it's too bad that the Xegl server never came to fruition. Having an OpenGL based Xserver would have been a good starting point for an OpenGL ES equivalent. I wonder if the Xegl project could be resurrected or at least examined for ideas. yes http://en.wikipedia.org/wiki/Xgl ...

but there are lower requirement options that are a better fit.


Thats what I thought. Seems to be the order of the day on most applications including browsers. Not hard to see why some people may have been miss lead and disappointed.

Re: First impressions - Slow, Scary & unfriendly

<t>Well I for one could well have ordered a Pi expecting more. I was initially put off by the need for an HDMI TV (or DVI) for decent video so did not rush to buy.  It was much much later that I read how slow it might be i.e. Pentium III<br/> <br/> The FAQ still has this as its first entry<br/> <br/...

Well one thing the 80's had was Byte Magazine. I wish it was still going and was due a month themed on Raspberry Pi. There just does not seem to be any good in-depth technical magazines any more.

Therefore you are probably talking about a SD card prepared specially for XBMC so if you try an run something else it needs to run in only a small amount of memory. Also thats why only the two ...

Please let me know when and where you publish the schematic and board for Gerboard?

As I might have a go myself to modify it for Matrix Multimedia E-Blocks.

Out of interest what PCB design software are you using? Eagle? DipTrace? Other?

Basically they connect hardware via a 9 pin D-shell i.e. 8 pins for the controlling port, 0v and power if needed to via a separate wire see http://www.matrixmul...
