I was just thinking nubus out of convenience, in the sense that speed doesn't really matter for a dev board with some LEDs and a few KB of storage, and there's a whole lotta different nubus machines that could be used for development, as opposed to figuring out which PDS form factor is being targeted. I'm not sure what, if any, difference nubus vs. pds makes in terms of declrom development. I suspect the Slot Manager treats them the same in terms of enumeration, declrom interpretation, and the driver unit table population. Anyway, seeing as how I'm a software guy, I find it unlikely I'd get around to building such a dev board.

I don't need any more information on declroms at the moment, but I'm sure I will eventually. I plan to pick up both those books in the near future, for sure. For now, I'll work on some of those tools I mentioned, if for no other reason than a further learning experience on directly invoking drivers without some Manager in the way (most *Manager calls are explicitly forbidden to be called from within a driver's Prime/Control/Status routines, so for a driver to invoke another driver, it must do so directly). Then hopefully on to some of the more directly useful ideas.

I just thought I'd post this useless but working driver in case someone else was interested in driver development. When I was looking, I found lots of incomplete examples, but nothing consolidated. Maybe it'll save someone time getting started at some point, who knows.
