Preserve keyboard, latches and original shell. CRT/mains work is specialist-only; record drive alignment and connectors before service.
- Record the complete model/SKU, serial/date label, board and bay/backplane identifiers, accessories and manual revision before disassembly.
- For integrated historical systems, follow the exact service manual for CRT, power and keyboard assemblies; do not assume a board or PSU swap is standardized.
- Keep original brackets, fasteners, trays, feet and front-panel parts labeled with the chassis. Do not force components into modified or incomplete specimens.
