|Designed when “real” typing on a quality keyboard was a required skill to use a $5000 IBM personal computer.
(pre-dates the then new mouse-click and graphical user interface operating system later to be known as Microsoft Windows 3.1 and 95)
|condition||Upper keyboard case and individual keys have been removed and fully cleaned by hand.|
|comments||Essentially the same design, construction, and quality materials as the more common IBM model M 1391401 (works just like any other keyboard). Key caps were customed for Sabre Travel Network reservations systems for American Airlines. Has additional distinguishing labels printed in green on side of key caps (FLIFO = flight info), (TKT = ticket info), (GFAX, FONE, SEG, I-SAB, CLSVC, CSS, IAS, SOM, EMEM, EOP, EOL)|
|comments||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 56 plastic 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.|
