Designed when “real” typing on a quality keyboard was a required skill to use a $4000 IBM personal computer. PC mag link
(pre-dates the then new mouse-click and graphical user interface operating system later to be known as Microsoft Windows 3.1 and 95)
conditionKeyboard 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.
commentsVery 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.
commentsThis keyboard is tested to work 100%. The keyboard assembly has been confirmed to be in functional, operational condition.
commentsNote: Keyboard bottom case a bit of plastic missing in lower right corner (aka authentic battle damage from 1986).  One could only speculate, but I imagine that it was probably caused by boss battle between a senior vs junior sysadmin back in the late 1980s arguing about the finer details of DnD spells vs potions and their effects on ethereal gauntlets.  The keyboard survived and is still fully functional to this day.. not sure about the other guy.  Included with this keyboard is IBM styrofoam packaging.
