NEC SN756 (10-pin plastic and ceramic DIP)

The NEC SN713B and SN756 are early Japanese-manufactured seven segment displays with a highly diffuse red filter. The SN713B is a fairly common device, but the SN756 seems to be a complete mystery. Little is known about this history of these devices. If you have any information about early NEC LED displays, please contact us.

Special thanks to Dr. Bruce Jarnot for donating these display.
