Texas Instruments sold their computer systems division at the start of the 1990s. I've read that that sale did not include the Explorer copyrights.
At the start of 2011 I got in touch with Robby Holland, then the head of TI's patent licensing division. Holland could not find anything about the computer systems division, or anything about the sale, or whether they owned the rights anymore. They did not have any of the project materials on hand. Holland said he would have someone look into the archives. When I tried to get in touch with him a few months later Holland was no longer with Texas Instruments.
