Is this the DM42n hardware with the R47 firmware preloaded? It looks identical, except for the colors of some of the keys, and I wouldn't think they'd have a separate hardware pipeline for it. I could be wrong, though! If someone were to obsess over their gear and tweak it until it was just so, this would be the company to do it.

Yes, it's the DM42n hardware underneath. The keyboard and overlay are different and the firmware is written from scratch using the WP 34S mathematics code. This has a lot more functionality than the DM42n does.
