I've seen a project on Circuit Cellar that used a microcontroller connected
directly to a NE2000 card making it network-enabled, but there were
insuffecient circuit and firmware details to build one (some of the project
was proprietary).

Does anyone have the pin/signal details for a standard NE2000-compatible
card, and perhaps the command set for setup and tx/rx? I can make my way
through the Linux drivers I find on the net (that's all the info I find
software-wise), but none of those offer detailed explanations of the
signals or commands.
