Single-Chip Linux Computer

Add some BlueTooth and you might finally have a decent platform to run all those household appliances you've been wanting to network at home. Interesting possibilities at least...
but really, serial ports? parallel ports? i'm not too sure that the scsi is going to win them any points either, but what the hell. they might have well integrated a video controler, an audio controler, and a 9600 baud modem to boot!
Well, I think they target embedded applications and not laptops here. Most embedded applications don't need sound or video capabilities and most engineers love to have serial and parallel I/O, because of their simplicity.
I'd agree on the parallel port complaint, but a lot of stuff out there that won't be going away for years still uses serial ports. I'm not a programmer, but I'd wager that good ol RS232 is a simpler interface to work with than USB and probably more robust over longer runs. I don't think something like this was designed for replacing your desktop.
So many complaints about the "obsolete" hardware - FUCKING DUH! It's a system-on-a-chip, running a common OS that is relatively easy to write software for, using tried-and-true peripheral technology and with enough horsepower to be used in all manner of embedded systems.
Sure, you wouldn't use it in a laptop or even a PDA, but that's not the target -- it can be used anywhere you need a simple PC to do simple tasks, but you don't want the huge and power-hungry old 386 you've got sitting in your closet/warehouse.
The thing's running Linux and is capable of networking for fuck's sake. Use your imagination.

You couldn't even fit the Windows bootstrap program on this thing, much less the web browser that is integral to the OS.
I want my rights back. I was actually using them when our government stole them after 9/11.
For some reason, even imagining a Beowulf cluster of these doesn't do the slightest thing for me...
I for one welcome our new SCOviet Russian overlords to whom all our base are belong.
It is available.
The chip itself is $40. The eval board for the ETRAX 100LX is available for $299 as well as a version with bluetooth for $495.
Finally, the order page for both of these is at https://www.axis.com/shop/technology.htm.

It's Christmas everyday with BitTorrent.
It only says its a 100 MIPS processor. (Million Instructions Per Sec)
The MIPS has 32 registers.

Nope, you're all wrong. It uses the CRIS architecture. See here for the architectural description.
I control the time!
The title is misleading. The device is a multi-chip-module, not a single chip computer. They have packaged a number of chips in a very small package, but it is not a single chip. A MCM will cost more to manufacture than a true single chip computer because it requires a ceramic substrate to be manufactured with very small trace widths connecting the chips that are placed on the substrate.
For a project I worked on at Keio Univ. in Japan, we ordered some of the Axis web cams, which use an older
version of the same chip, as well as some of the developer boards.
The system works as advertised; developing software and
deploying it is very easy, you just do a "make" in the source directory on your host, and it builds the flash rom image, and you download it via ethernet with a single command. You can ftp over to the board to upload binaries or other files, and there's a telnet client.
The only problems I had with the dev board were that it doesn't really have much useful I/O on it.
It has three serial ports and 16 bit parallel port, which can be used as an IDE drive or USB port, but at the time we got the system, you had to kind of roll your own interface. And at the time the drivers for the parallel port weren't
shipping standard so I had to write my own kernel
driver for it.
