manufacturing dot-matrix (5×7) character generators (CG) for airport arrival and departure time displays. It also began manufacturing a clean-looking fixed-font (ROM-based) CG sold as the Chiron I. It featured the ability to record and retrieve lower thirds and full page text displays for news departments of TV stations as an alternative to art cards, slides or scrolling black felt. The company built its own multi-track magnetic storage device, the VidiLoop, based on a two-foot loop of computer tape in a thick clear plastic housing. On the Chiron I, it was used solely for title storage. It was also used on a few early Chiron IIs, but due to increased storage requirements it was replaced by Shugart SA901 8" floppy drives as soon as they were available. The name Chiron was already registered in California, so by changing the I to a Y in the 1970s they were able to keep the familiar-sounding name and became initially Chyron Telesystems and, later still, Chyron Corporation, capitalizing on the product's name recognition. The Chiron II featured up to six loadable fonts (typefaces) with, for the time, very high video resolution. The display circuits were running so fast (27 ns) that the fastest ICs available were used and had to be hand selected during manufacture as not all samples were up to par. It was also the company's first unit to incorporate a 16-bit mini-computer known as the DataMate-70. That processor's code base was used in the Chiron IV and 4100 series systems, which were the workhorses of the mobile sports graphics industry from the late 1970s through most of the 1980s. Programs and fonts were loaded from loop or disk into computer style magnetic core memory. As the font data access needed to be done more quickly than a single core memory could achieve, four core boards were used in parallel to provide faster access. It was also the first CG that had non-monospaced fonts with adjustable inter-row and inter-character spacing. All of that capability came at a cost too dear for many small market TV stations and so a spin-off of a project for NBC became the Chiron III (later IIIB); a less capable system that was adequate for many TV news departments was developed and sold. It became the first mobile graphics systems of ABC Sports under Roone Arledge. It was he who pushed the increased use of graphics in sports
