The subsequent multi-user version of StarText, developed by Serge Stein, was written in DIBOL and ran on Digital Equipment VAX 11/750s connected to banks of 1200 & 2400 baud modems. This version provided a menu of content including the Star-Telegram's news and classified advertising, and provided messaging between subscribers (early email), Grolier's encyclopedia, American Airlines Sabre flight schedules and home banking to a group of over four thousand dedicated computer users. Users could define their screen size to the system which would then deliver only as much text as would fit on the screen giving the user the opportunity to read the content before 'paging' on to the next screen of text. At one point billing for this service was based on the number of words sent to the user.
