This is cool and all, but if it's called a "linux stamp" it should at least have some I/O capability other than a serial port. (I am thinking of "turn on the LED" type things.) The basic stamp does really well here, despite being proprietary, horribly limited computationally, and locked-in to one of the worst programming languages ever designed (PBASIC). I remember it offending my sensibilities even when I was in middle school :)
Programming I/O in Haskell would be fun. What would you call the "turn on the LED" monad? :)
It has a USB host port, which at least means that the universe of USB devices is available. You can get USB RS-232 devices, parallel I/O ("printer ports"), cheap ADCs ("joystick ports") etc...
But I agree. A tiny microcontroller board is really only useful for what you can control with it, and out of the box this doesn't do much. Would it have killed them to toss a dozen bidirectional TTL ports on the thing?
Have a closer look at the photo. There's rows of holes for connectors along the top and bottom of the board. I see one set is labelled JTAG. It looks like the tracks and holes are there for soldering on other I/O connectors if you wish. Oh, and there's a LED in each of the bottom corners. ;-)
