Compatibility and service
- 68020 bus board, clock/reset and 5 V; not 68000 pin drop-in
- Package/mask suffix matters; check part and datasheet revision
- Photograph marking/package; preserve board schematic
- Confirm board manual, exact CPU support list, firmware, voltage/power, memory and cooling before use; never force a package.
Service & archival notes
Photograph marking/package; preserve board schematic
Photograph package, markings, contacts and date/lot codes before repair. Log host board, BIOS/microcode, memory, cooler, condition, provenance and source revision.
