| condition | Keyboard pre-selected as good candidate and passed initial testing to confirm mechanical condition. Upper keyboard case disassembled and individual 101 keys have been removed and fully cleaned by hand. Inspection of interior plate. Any missing rivets drilled out and replaced with M2 precision screws to restore internal integrity. Interior plate vacuumed to remove foreign debris. Keyboard re-assembled and re-tested post-cleaning. Individual photography of rear label. Photo gallery of typical restoration workflow. |
| comments | Keyboard has had all plastic rivets removed and a 100% full bolt/screw mod for this exemplar 30-year-old model M keyboard. Thicker, heavier chrome curved plate that was only found in early model M’s early in the production lifespan such as 1390131 and 1391401. (see extra photos below) |
| comments | This keyboard is tested to work 100%. The keyboard assembly has been confirmed to be in functional, operational condition. |
