Model-specific archive record. Enclosure labels do not always identify the installed mechanism or host controller; preserve the full suffix and inspect the unit before connection or service.
MODEL IDENTIFICATION: Commodore Amiga A1011. Photograph the nameplate, serial, connector and power rating. Verify revision-specific instructions and inspect any replacement mechanism before use.
Recorded specifications

Compatibility and preservation caveats
A1011 has no external pass-through on this model; it must be last in the chain. Do not rely on A1010-family assumptions. Verify nameplate/mechanism and avoid damaged media.
Inspect for corrosion, contamination, cracked plastics, damaged shutter, cable strain and prior repairs. Do not insert damaged media. Record host, OS, controller/driver, drive label, revision, media condition and acquisition settings. Preserve original images and document conversions separately.
