Today I managed to complete an EPROM replacement without really knowing what I was doing. Hope these help others.
Unclip the aluminum connector by pulling up.
Remove 10 mm nuts on either side holding EML in place.
The red circles are the screws to remove, the green, the retainer pins to be pulled out. Straighten all metal clips around the perimeter.
Retainer pins pulled out with needle nose pliers.
Remove plastic retainer and plastic sheet.
Use needle nose pliers to pry apart the board so the connectors pop apart.
The trickiest part is disengaging the upper half of the board from the electrical connector. The two guide bars at either end must be disengaged by inserting screwdrivers behind them and then prying (gently) the plug toward the centre (CDN) and at the same time pulling back on the board while lifting the ribbon connector end for clearance.
EML open. Note the plastic retainer over the EPROM. Stick a small screwdriver in each slot and tip outward at the bottom. Make sure you put the new EPROM in with the notch at the proper end (toward the centre).
Reverse to re-install.
