You can basically just jam 'em right in there! The main rules difference between the two is what happens when characters go down (in MB they die; in OB they get incapacitated or dismembered and then have their bits replaced with cool cyborg gear).
Converting to CY_BORG takes one simple rule:
Orc-borgs get to roll Presence when they would roll Knowledge, and anyone trying to work orcish tech can use Presence instead of Knowledge if they wish. Orc tech runs on vibes and intuition!
Sorry for the tardy reply (I don't get notifications for these)!
