Hi all, I have this coax network card installed in my LCII and was wondering what that PLCC style socket was? It looks like the same sort of ones that hold a 68882 PLCC FPU. Can anybody shed some light onto this?

P.s. Attached an image of a different Farallon card but fits the same models, it just has a RJ45 socket instead. Il get pictures of mine later if it will help?
