Understand before intervening
Labels, connections, earlier repairs and additions should be documented before work begins. Two examples of the same model may carry different histories. A period modification can itself be evidence.
Operation is one possible goal
Stabilisation may be preferable to returning an object to service. The choice depends on condition, rarity and collection purpose. The Computer History digital history collection’s PDP-1 project illustrates the importance of reversible work where feasible.
Record the intervention
Replacement parts, photographs and a work log help future researchers interpret the result. A successful demonstration does not establish permanent reliability.
Careful presentation
Old power supplies and displays require qualified assessment; this historical account is not a repair procedure. Exhibitions should identify restored or modern replacement elements. Responsible restoration reveals a machine’s capabilities without erasing the evidence of its working life.
