World's First Linux Computer In A CF Card

An anonymous reader writes "LinuxDevices reports on the world's first Linux computer to fit inside a CompactFlash card. The 'Compact Flash Computer' (CFC) can be mixed and matched with third-party CF cards to instantly create minuscule Linux systems based entirely on CF cards. A wide variety of third-party CF peripheral cards can be used with the CFC, including RS232/485, Ethernet, Bluetooth, USB, 802.11, GSM, GPRS, GPS, and more. A combination power supply / bus expander module on a separate CF card, as well as a tiny 8-slot CF card backplane, are available as options." An anonymous reader adds "The card is based on a Freescale MPC5272 system-on-chip processor and contains 32MB of SDRAM and 8MB of Flash memory, and it comes with a uClinux based operating system and GNU development/debug tools."

Re:Maybe not the first?

That is not a Linux computer on a CF card. That is a Mini-ITX-based computer _with_ a CF card.

The custom-built pda

You know, this could be a great way to bring upgradeability and extreme customizeability to portable devices.

One could imagine a sleeve where you plug in a cpu card, some data storage cards, a wifi card, and so on. Sleeves could be upgraded to provide new peripherals. You would use firewire, usb or some other generic protocol to provide the interface between the sleeve, the cards, and the outside world (possibly using stub cards that transform a cf card to a usb data storage card).

That way when you need a bigger screen, you'd buy a new sleeve and dock your old cards into it. Cpu not fast enough? Just upgrade the cpu card, no problems with having to replace the entire pda.

Why hasn't this been done yet? It seems like an untapped market just waiting to be discovered.

Because most people, unfortunately, are not geek hobbyists, and think of computers in terms of application, not of mechanism. To them, this reconfigurability is just additional cost, complexity, and fragility to get a "follow the directions to assemble it yourself" device that performs some task that they want to do, like store lists of phone numbers. Sure, it drives us bonkers that we don't have a pretty interface and better support for the I2C bus (or internal USB in cases), interesting input (knobs, sliders, etc that can be interfaced with) devices, cheap interesting output devices (LED/LCD/VFD front-panel displays), thermometers, and the like. The typical computer user, though, doesn't give a damn about extending or reconfiguring their computer, because they want to accomplish a task, and don't really want to "figure out what to do to their computer to accomplish that task".

Sigh.
