Options for IBM model M15 in original IBM box. To our knowledge, best remaining

| comments | Keyboard is unique in that it is the only mechanical buckling-spring keyboard made by IBM that is fully adjustable in terms of ergonomic position. The two halves of keyboard are connected at ball-joint and can be separated into two separate pieces. Split space bar has erase-eaze feature. Keyboard can be also adjusted to various heights to accomodate most comfortable typing angle to alleviate stress on hands, wrists and arms. |
| comments | Very few were ever made by IBM. Ergonomic keyboards are always very expensive compared to traditional keyboards... but we figure it is easier to buy an ergonomic keyboard than to pay an orthopedic surgeon to surgically operate and to rebuild your hand/wrist/arm. Very limited item. We have been selling model M keyboards online for 10 years and have sold more than four thousand two hundred (4,200) new and refurbished keyboards since our first ebay sale in 2002. This is only the see for more info |
