Highway Communicator

Text Messaging system I created in 1980 - 1981. Used in different vehicles for 18 years. Z80 microprocessor running at 1MHz. 16K RAM ran operating system and messaging editing application written in machine language. In the days before most people had home computers, this attracted a lot of attention, often creating a highway-blocking convoy of drivers all wanting to read what I was typing. See technical details.
