LED message sign turned into counter

I need some help... I have a bunch of LED message signs that I would like to turn into large counters (1,2,3,4 ). Anybody have any insight into how to do this? I am really stumped. Daniel

A microcontroller must count and feed the sign's interface.
How to interface depends on what kind of sign.

Maybe this search link will be helpful:
Google Betabrite Interface
Betabrite is a brand of LED sign with memory that I have.

A totalizer is an LED counter sold for using to count (usually things).
Many calculators will count likewise with the following "input":
C 1 + = = = = = = = = = = = = = = = = = = = = = = = = =
Also search for clock and watch projects for more ideas.
