5x7 LED Matrix Scrolling Display

[roycarlson]

I guess I was more fustrated at the ebay vendor for not providing the code or schematic.

If these is a way to paste a picture here I would. I have a few 16F887 and 16F877 40 Pin Pics laying around to use. I am trying to figure out how the board has the two 74HC425s configured as it appears it is using Pic Pins 2-5, 7-11 and 15-25 for the columns via the transistors (20) to the LED columns.

It also looks like pins 33-39 are connected to pins 2-8 of the 74HC425 chip #1 while there is crossover to the second HC425 chip via pin 2 to pin 18 on chip #2.

The LED Matrix have red or green outputs which are controlled by toggle switch. And it appears swith 29 & 31 are conected to ground via push button switches.

** Is there a way to paste the photo of the board?
