In the last few weeks I've been playing around with embedded Linux. Bert, a flatmate, brought two old thin clients from his work. They're bot Wyse WT8440XL devices, containing a 400Mhz K6-II processor, some peripherals, and a "DiskOnChip". This last one is flash device that is used instead of a hard disk. It's soldered directly onto the mainboard and as far as I can tell, it interfaces with the system directly into the memory controller, similar to what a BIOS chip does. Anyway, this means I have no hard disk to put a full OS on, but only 96MB of flash storage (And yes, I know I can just plug in some USB storage, which is even what I do for testing, but not using the internal flash chip wouldn't be half as much fun :-p)
