In our latest Parallel Port entry, we go through the process of getting our LAN Bridge repaired and restored. While we demonstrated a working LAN Bridge in our first video, this one wouldn't even power on. It would be really neat to get the fiber optic transceiver working, so let us know in comments here or on Discord if you've got any ideas for next steps.

Let us know if you like these deeper dives into devices like this one, and thanks as always for your support!
