=== GLUE and MMU Custom Chips === The Mega STE uses revised GLUE and MMU gate arrays that support 16 MHz operation. These are surface-mount custom Atari parts and are not field-replaceable without specialised equipment. * '''GLUE failure:''' No video sync, no bus arbitration. The machine appears completely dead despite good power. * '''MMU failure:''' RAM not accessible. CPU halts immediately after reset. Both are rare failures but can occur from ESD damage or voltage transients.
