Packman

If you've already installed RISC OS RC5 on your Raspberry Pi, you do not have to burn a new SD card with dd to get RC6. You can use PackMan.

I thought you said Puckman


!PackMan is the package manager for RISC OS. It will connect to a repository and download your selections, or perform an upgrade.

The Packman user guide is here:
https://www.riscosopen.org/wiki/documentation/show/PackMan%20User%27s%20Guide

Note that after the upgrade, your config.txt will be overwritten, so if you made modifications (for the hdmi modes or the memory split), make a note of them.

Nut Pi for RISC OS

RISC OS Open is bringing some interesting things to the table as far as the Raspberry Pi and RISC OS is concerned.

They have a package of commercial software for RISC OS, specifically designed to run on the Raspberry Pi, at a discount.

What is cool is that it comes on a Nut Pi branded SD card (a usb key might have been better, in order to transfer to the Raspberry Pi, but still, nothing a card reader cant fix).

It includes Photodesk 3.12 which retails by itself for £84: Photodesk. It also comes with 19 other software programs originally for the Acorn computers.

The Nut Pi SD card is available here: https://www.riscosopen.org/content/sales/nutpi, for £35.

My suggestion for RISC OS Open: add a link in other currencies. In particular in US dollars.

MagPi

I just received a printed copy of The Mag Pi #6, from the folks at ModMyPi.
I do have the PDFs for #1 to #6 but when I heard somebody was printing it at a commercial printer, I figured I had to get a copy. Although it is #6, it is the first copy to be printed on paper.

It reminded me of the good old magazines I would get as a kid such as InCider, Compute etc. BTW, digging in my old magazines, I saw that Compute was published on Wendover Ave in Greensboro, NC. That's interesting to me because that's not too far from where I'm at.

And speaking of this area, if you live near it, I would like to suggest you check out PYPTUG. We'll be having a workshop with Python and the Raspberry Pi on November the 10th.

Anyway, back to The MagPi:

QR Code, even

And speaking of ModMyPi, I ordered a "surprise" color mix case. It's the cheapest option they have, but you never know what colors you'll get. Red and Black, I think that worked out well for me:

Color contrast works well with my Motorola LapDock RISC OS machine.

Imprimer son boitier

Il existe des douzaines de boitiers pour le Raspberry Pi sur le marche. En acier, en acrylique, en thermoplastique, en polyvinyle, en bois, en aluminium, en cuivre, et, pourquoi pas, en papier!

L'avantage ici, c'est que c'est gratuit, si on a une imprimante. Attention toutefois aux marges et au type de papier. En effet, certains des PDF sont pour le format A4 et d'autres pour US Letter. Il faut donc faire un ajustement des marges etc si on n'a pas le bon papier.

RISC OS

Acorn Proton


Que es? Al principio de los anos 80, el Acorn Proton paso de computadora obscura, un prototipo, a un de los mas famosos ordenador, a causa de la BBC. La máquina fue lanzada como el BBC Microcomputer (Beeb Micro), especialmente para ponerles en las escuelas. Fueron vendidos casi 1.5 million de machinas durante 12 anos, la mayoría en Europa. En los Estados Unidos, el Apple ][ fue sin competición en las escuelas.

Hay muchos detalles en wikipedia.

Acorn Archimedes


En 1987 empezó el Acorn Archimedes y el BBC Archimedes . Fue el primer ordenador personal con CPU RISC ARM de 32 bits.

RISC OS

RISC OS es el sistema operativo de los computadores Acorn con CPU ARM. El Raspberry Pi también es basado en el CPU ARM, y es posible ahora de utilizar RISC OS con el Pi.

Hay una pagina en ingles aqui

Preparación


Descargar el OS aqui: riscos-2012-10-16-RC5

Ponerlo en una tarjeta SD con dd. Si la instalación es directamente de un Raspberry Pi con el OS Raspbian, ver este articulo: autoreplicación.
Pero en vez de:
sudo dd bs=1M if=2012-09-18-wheezy-raspbian.img of=/dev/sda 
hay que hacer:
bunzip2 ro519-rc5-1876M.img.bz2
sudo dd bs=1M if=ro519-rc5-1876M.img of=/dev/sda

Cual sea el sistema operativo, el GPU busca el fichero config.txt. La definición se encuentra en elinux.
