Publishing rights for a lot of the classic MicroProse games seem to currently be held by Retroism: https://retroism.com/

This includes the original MicroProse Mighty 8th (https://retroism.com/b-17-flying-fortress-the-mighty-8th/), along with the Silent Service games, F-117A and F-19, the original Sid Meier's Colonization and a bunch of others. Though there are some notable MicroProse titles missing from their catalog: M1 Tank Platoon, the original Gunship and Gunship 2000, and F-15 Strike Eagle III all jump out at me.
