date 01 DEC 88

condition Extremely rare item from 1988.  Keyboard originally came with early IBM industrial computer and color is typically described as gray, but we think that military olive drab is a more accurate description of the color.
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.
comments Very nice IBM model M keyboard with silver IBM logo.  Has additional stabilizer bars under numeric + and Enter keys in addition to stabilizer under space bar.

All 56 plastic rivets have been expertly replaced with M2 screws for ensure for a tight and crisp keyboard feel.

Includes 4 blue 7/32″ screws primarily found in 1986 model M keyboards.  Includes original IBM cardboard box and white styrofoam packaging (see photos).
