He wrote the original script but the director and producers butchered it so badly that Frank Miller swore off movies until the recent Sin City project.
If the Director of Robocop 2 had played nice who knows what movies we might have seen by now.
A couple of years after the Robocop 2 debacle, he wrote Robocop VS. Terminator for Dark Horse Comics. It was illustrated by Walt Simonson, and feels like the story he wanted to do on screen.

Frank Miller's Robocop series wasnt bad. Its kinda too short imo. Robocop 1 and 2 are among my top 5 movies of all time. Hes also one of my favorite characters of all-time. Robocop is super badass. I loved the Robocop vs Terminator threads to talk about how much Robo would own the T-800 model. Robocop vs Terminator series was good as well. Freddy vs Jason and Aliens vs Perdator have already been done. All thats left to make is Robocop vs Terminator.
Heres some scans of Frank Miller's Robocop being badass. Enjoy.
