you can find a number of embedded Linux distributions - for a simply start you might want to grab MiniRTL - it fits on a single floppy and can be transfered to flash/IDE-disk for an embedded system aswell. 128MB ram is more than you will ever need so you should be able to operate the entire system in a 32MB RAMDISK giving you good performance and enough space to build a very large embedded system. On MiniRTL V2.3 and V3.0 you actually have a module that can produce pulses on a parport-pin (its just the parport module from rtlinux), modifying this for some other hardware DIO should be trivial. You can find MiniRTL at: ftp://ftp.thinkingnerds.com/pub/projects/minirtl/ And some docs on using/building/modifying it at http://www.fsmlabs.at/documents.html hofrat -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] -- For more information on Real-Time Linux see: http://www.rtlinux.org/
