Description
| part# | 1391401 |
| serial# | 2499723 |
| date | 03 NOV 87 (39 years old) |
| IBM logo | black logo on white background |
| cable | removable SDL, coiled cable, ps/2 connector (used SDL to ps/2 cable, standard length) |
| key caps | removable (two piece, key stem + key cap) |
| key switches | clicky = buckling spring |
| 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) | |
| 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. 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. |
| comments | Note 1: New old stock Unicomp electrical membrane circuit sheet installed. Previous owner painted curved metal plate black. Note 2: Some original wear/discoloration of the authentic 1987 IBM model M rear sticker. Does not affect functionality. Note 3 : Worn lettering on Esc and numpad Enter keys. Note 4: Bottom keyboard case is missing a part of lower right hand corner. (perhaps historical battle damage from epic mid 1980’s cubicle keyboard warrior battle? (see 2nd to last photo in series) LOL) |
| comments | This keyboard is tested to work 100%. The keyboard assembly has been confirmed to be in functional, operational condition. |
