Subject: Re: How the heck do I get started?

As for Ben's remark on Linux Device Drivers, I don't really have any
hardware that I could write a device driver for, would a USB mouse do,
or is that too complex? I do have a microcontroller or two lying
around, would be feasible to write a software bootloader for them?
