About this keyboard type
The Model M industrial keyboards were the first discreet and PC-compatible Model Ms available, originally shipping with the AT-class IBM 7531 Industrial PC starting in May 1985. Compared to the IBM Enhanced Keyboard, industrial Model Ms are essentially the same underneath but feature a grey-coloured case designed to hide the dirt and damage expected to be inflicted upon the device within an industrial environment.
