Matsushita Central Research Lab claims to have developed the first implementation of B-Tron, the version of the Tron operating system for office automation and business applications: the company will be slapping in requests for 93 patents on the implementation for use on personal computers, and is entering into negotiations with Professor Sakamoto, who originally dreamed up Tron at Tokyo University on sharing of intellectual property rights in it; Matsushita has implemented the thing on an 80286 with 2Mb memory, 20Mb disk, 3.5 floppy, Tron keyboard and bit-mapped display, but says that it will be another two to three years before B-Tron products are ready to appear on the market.
