Data Display Question

[Dennis Benjamin]

I am attempting to resurrect this sign (see attached photo). It is a Data Display sign. Data Display went out of business years ago. I know how the sign works and that I can purchase a RS232 to RS485 converter off of Amazon. What I am looking for is the sign software program that I can use to interface with it. Does anyone have a copy of that program? Or know where I can get a copy? It is NOT the Simply Theatre Signs (STS) program that Adaptive Technologies uses. Any help would be appreciated.

if you know the original domain I would check the internet archive waybackmachine.

I don't know, for sure, but I think that Data Display has either been taken over by or has morphed into the company, now known as, Daktronics:
