|condition||Very nice specimen of IBM original model M space saving keyboard in 84-key format (no number pad). Includes original SSK keys with front-side printing to show numpad functionality (7-8-9 = Home, Cursor up, Pg Up; U-I-O = cursor left, cursor right); J-K-L = End, Cursor Down, PgDn) and NumLk – Scroll Lk key. Includes IBM original 1391472 extendable feet (which differ from 1391401) feet.
|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 plastic rivets drilled out and replaced with M2 precision screws (full bolt/screw mod) to restore internal integrity (see last photos in description below). Interior plate vacuumed to remove foreign debris. Keyboard re-assembled and re-tested post-cleaning.
|comments||Similar to the classic 1391401 or 42H1292 buckling spring keyboards, but this keyboard only has 84 keys and does not have numeric keypad. You can still switch to numeric keypad mode by using the key combination of “SHIFT” + “NUM LK/SCR LK” keys (between print screen and pause keys.)|
