The IBM Industrial Space Saving Keyboard was a variant of the IBM Space Saving Keyboard designed for blending in with industrial environments - in particular, heavily within the automotive industry. In a familiar fashion to the relationship between the IBM Enhanced Keyboard and IBM Industrial PC Keyboard, the only difference is the grey casing designed to hide the dirt and discolouration expected to be inflicted upon the device within an industrial environment. Like the full-sized industrial keyboards, these are usually sold at a significant premium.
