The Mikrotik Routerboard finally showed up and I mirrored port 2 egress/ingress to port 3, started up showeq on the Odroid-C2, told it the IP address of my Windows gaming machine and loaded up Project 1999 (please note I'm only doing this on project 1999 since I no longer play Everquest and just wanted to test this out on the Odroid C2).

It crashes with the following (it's been so many years since I off-lined the my parts of the brain used to hack showeq that I'll have to research how to fix it). However it does run fine on the Odroid-C2 so that would be a great low-cost showeq box (fanless, quiet with 1gb nic and 4k monitor support).
Until I recall how to fix the showeq code I can only report it looks great and starts to draw the map.... anyway here is the error:
