IBM Industrial Keyboard with Pointing Stick

More about this type of keyboard...

The IBM Industrial Keyboard with Pointing Stick was a variant of the standard Model M13 designed for blending in with industrial environments. In a familiar fashion with other Model Ms that had an industrial version, the main difference is the grey casing designed to hide the dirt and discolouration expected to be inflicted upon the device within an industrial environment. These were first produced for IBM by Maxi Switch featuring TrackPoint II pointing sticks, but were also later produced for IBM by Unicomp and came with Unicomp Pointing Sticks instead.
