Mark. I just got a board that I am going to experiment with. See the link for pricing below. I didn't spend quite that much 'cause I piggybacked on another order, so I got some volume discount. Check out these features: CPU: 200Mhz ARM9 with full MMU RAM: 32Mb FLASH: 32Mb NAND Flash Network: 200BaseT Ethernet Serial: 3 RS-232 Ports standard Digital IO: 30pins Analog: 2 channel 12 bit ADC Expansion: PC-104 8 bit connector (16 bit is optional) WatchDog Timer Power: < 1 watt max. 1/4 watt nominal Out of the box this board runs Debian ARM. You want Perl and its not on your system - 'apt-get install perl'. You can mount its root file system on NFS, giving you room to put compilers and anything else that you could want. I got the optional SD Card giving me the option of booting from the SD card so that I can install the full development kit on the root device. Its actually a fast enough processor that you can run gcc and gdb on it without too much problem. I am very impressed by the manufacturer 'cause they have lots tools (there is a full cross compiler that you can download and run from your PC linus box so that your desktop linux system is your development system) of documentation and sample code on their web site. Plus there are plugin cards (daughter boards) to do everything from add another ethernet port, add a 2.5in disk drive, add GSM wireless to adding VGA capability. I have just started to read about real time linux kernels (again from their web site). So, whatever you want to do this board/software combo is capable. If you have wanted to have a board that will really let you go nuts with low level stuff this one is affordable and has all the tools that you could want. The link to features and pricing is right here: http://www.embeddedarm.com/epc/ts7260-spec-p.php I have some things in mind for this board.
