"It seems like companies must be sending 128k MIPS handhelds to the landfill at this point, so giving them to us to use in teaching would be a win/win, since they'd get a tax writeoff and some good will instead. But even if they cost $20/ea, that would be fine. Any suggestions on what hardware to use, or what companies to contact? Remember, there must be a convenient way to download executable code into them, using a cable rather than a flash ROM. And we're pretty much a Debian GNU/Linux shop, so a working cross-compiler based on the GNU toolset would be best. An emulator would be even peachier, so students could debug without downloading the code after each little change, although that's not strictly necessary."
