Variant of a Model M15 Adjustable Keyboard
Variant of a Model M15 Adjustable Keyboard

The Model M15 was a highly adjustable ergonomic tenkeyless-like keyboard based on the Model M1/M2 design and was branded as either the IBM Adjustable Keyboard or Lexmark Select-Ease Keyboard. Being the only ergonomic keyboard as per today's standards that IBM ever marketed, the Model M15 features a high degree of customisability; including split, tilt, swivel and tenting capabilities. For convenience, the arrow keys are duplicated on both halves of the keyboard and the split spacebar has an Erase-Eaze feature. It is a candidate for the last IBM-sanctioned buckling springs keyboard design.
