Included its own scripting language (Network Command Language, or NCL), and an optional tailored front screen for 3270 users (Easinet).
Marketing rights were acquired by Cincom Systems from Software Developments in 1984, after which Cincom and SDI both continued Netmaster development. Software Developments later attempted to end this agreement, resulting in a legal battle between the companies.
Systems Center Inc acquired both Software Developments, and the Netmaster marketing rights from Cincom in 1989.
