Well, not much to tell here. PGA 128 socket base. Press L 7.4 female gold pins from Aliexpress into the holes to get a PGA 128 socket for your MC68030 or similar CPU's. Do not mix up the sides of the socket, as hole pattern is not symmertical!

WARNING: CPU's can get HOT. Sometimes nominally, sometimes because of unexpected failures. Don'use any filaments which have low plasticity temperatures for this project. Use ONLY engineering grade, high temperature filaments. Something that starts to plasticize over 100 degrees celsius.
