Hints for finding the hardware connected to staging drivers

Hi, I currently have a hard time to search for the real hardware behind some of the staging drivers. For example within the 'kpc2000' driver, only the Kconfig file gives a hint a to the manufacturer 'Daktronics'. But a google search for 'Daktronics kpc2000' or 'Daktronics kp2000' yields nothing. So, is there some kind of datasheet for those information? Or do I approach this problem incorrectly? Thank you in advance. Greetings Sebastian
