Hi,
Recently I got a gaming machine display board from ebay, It has 6 5x7 matrix ,32 bar graph Led's and 4 MM5450 controllers. Is it possible to use these controllers with AVR or PIC to make a moving display..? I am attaching the circuit and the picture of the pcb..
Definatly you can program your own microcontroller and can make it moving message display. Alternatively you can visit **broken link removed**, here you can buy moving message display product at cheap durt price.
