Description
This is a case mod for any Compact Macintosh (128k, 512K, Plus) that has a bulky upgrade card installed inside. I designed this for a 512k with a MonsterMac card. Its purpose is to make removing and inserting the logicboard less difficult.
For this to be used, you must clip off the three little channels that you would normally slide the logicboard into, on the side of the metal opposite the analog board. With these channels gone, you insert the logicboard from the bottom, and then clip on the 3d printed case mod into the circles just above where the channels used to be.
