Ha, the pass-through version is possibly a long ways off. I had grand plans but the mechanical considerations mean that there will probably have to be a few trial-and-error revisions before I get it right.
If you do want an ethernet card with a pass-through slot, a fellow on the 68kmla forum is building such a device already: https://68kmla.org/bb/index.php?threads/fs-se-30-ethernet-ac.... His card is hardware-compatible with the Asante MacCon card for the SE/30, which is extremely neat, but requires sourcing no-longer-produced components in order to build it. The idea with my card is to build something with modern parts that are easier to find.
