The Skytone Alpha-400 is a Linux-based low-cost netbook with a 7 in 800×480 LCD screen. Its measurements (length×width×depth) are 210×140×32 mm and it weighs 0.65 kg. It is made in China by Skytone and Exon International Technology Co Ltd, with the former providing the GNU/Linux software and the latter producing the hardware. It uses a Chinese Ingenic Jz4730 336 MHz MIPSII-compatible one core 32-bit system-on-a-chip (SoC)[3] with 128 MiB of SDRAM, and a 1–2 GB solid state drive.

The Skytone Alpha-400 was designed with low cost and child-friendliness in mind, some versions being sold for as little as $130 retail. There is an option to swap the standard theme with a children's theme. It also comes with applications geared toward children, and a Flash player to play animated children's songs. The Flash player is not built into the browser, so Flash-dependent sites such as YouTube will not work, but a standalone Flash player is available to run .swf files and can be used to play Flash based games, and such.

Features

The Skytone Alpha-400 uses a customized version of Linux, based on a 2.4.x kernel, with a user-friendly interface optimized for children.

The Linux desktop is implemented as Kiosk software, meaning that nothing the user can do can modify the available applications, and no new applications can be (easily) added or removed.

Browsing can be done through the use of the built in browser called Bon Echo, an Alpha release of Mozilla Firefox 2, using the built-in 10/100 BASE-T Ethernet port, or the integrated 802.11 Wireless LAN, but the browser does not support Flash, meaning that Flash intensive tools, such as YouTube, cannot be used. However, recently Exon, the original design manufacturer of most of these devices, announced full support for YouTube and most Flash enabled websites.

The device sports three USB ports, a small but fully functioning keyboard, a touchpad, stereo speakers, and a 2 cell 2.1 Ah battery.

The Skytone Alpha's processor uses as little as 0.2 W of power, and does not have a heat sink, and thus no ventilation openings. Some versions have extra features like a VGA video port, or a USB On-The-Go port.

Available distributions

So far all distributions for this device use the 2.4.20-celf3 kernel. The kernel itself is not on the root file system itself and gets loaded by u-boot.

Other similar devices by Exon/Skytone

The successor of the device, the Alpha 400P, comes with a 416 MHz XScale, fifth generation ARM architecture, SoC (likely a Marvell PXA27x), USB 2.0 and up to 256 MiB of DDR2 memory.[15] Another similar device comes with the 248 MHz ARM SoC AK7802Q216, 64/128 MiB of DDR RAM and Windows CE 5.0.[16] Skytone announced another device called Alpha 680 running Android[17] that features a 533 MHz Jade Tech Z228[18] ARM CPU. The Alpha-680 has a rotatable touchscreen that can be turned and flipped over, so that the unit becomes a tablet computer.[19]

Another similar machine produced by Exon, but not sold by Skytone, comes with an x86 legacy compatible 800 MHz DM&P PDX-600 SoC CPU and is thus able to run Windows XP.[20]

It uses a XGI Volari Z9s GPU without 3D acceleration. As it is usually sold with Windows XP preinstalled, its default configuration has 512 MiB DDR2 SDRAM and 4/8 GB flash. It is also available with a built-in 0.3 Mpixel camera. This version was first presented at CES 2009.[21]
