(pre-dates the then new mouse-click and graphical user interface operating system later to be known as Microsoft Windows 3.1 and 95)
|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. All rivets on this keyboard were completely drilled out and replaced with a total of 58 individual 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.
|Very nice IBM model M keyboard with rare internal extra heavy-duty shiny plate and silver IBM logo. Has additional stabilizer bars under numeric + and Enter keys in addition to stabilizer under space bar.
|This keyboard is tested to work 100%. The keyboard assembly has been confirmed to be in functional, operational condition.
|Each and every one of the original rivets, have been expertly replaced with M2 screws for ensure for a tight and crisp keyboard feel. Entire restoration procedure took about 3 hours of detailed work. Of particular note is the dipped chromate coating on the curved metal plate and quality of the components used on the internal keyboard controller board. Note, some minor marks in top case from previous “cubicle battle damage”, see last 2 photos. We are particularly proud of the outcome of this model M restoration and have taken several pictures to show the quality of this keyboard, as it shows one of the earliest, finest (and heaviest) IBM enhanced keyboard designs which ultimately lead to success of the model M keyboard lineage over the past 30 years.
