| Designed when “real” typing on a quality keyboard was a required skill to use a $4000 IBM personal computer. Â 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) |
|
| cable | attached, coiled cable, ps/2 connector |
| key caps | removable (two piece, key stem + key cap) |
| key switches | non-clicky (rubber dome) variant |
| condition | 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.  Any missing 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 | Same solid construction and internal components as many model M keyboards, but buckling-spring assemblies replaced with rubber-dome membrane. Note, the keys on the 71G4644 and 01M1525 rubber-dome model M keyboards are not the same as 1391401 keyboards. Also note, that a properly restored 71G4644/01M1525 will have a small spring on the tube underneath the space bar. |
| comments | This keyboard is tested to work 100% |
