| - | An early form of Command Control for model railways, Zero 1 was launched in 1979 and systems incorporating the technique were marketed by Hornby Hobbies and Hammant & Morgan. This really was the FIRST DIGITAL SYSTEM, predating our current NMRA DCC system by MANY years, hence the name given to it "Zero 1"; digital, binary notation, it all revolved around the Texas Instruments TMS 1000 microprocessor. Now obsolete, having been overtaken by the DCC system, Zero 1 pioneered the concept of controlling model railway motors by establishing a constant track power source that included control signals to define locomotive identity, speed and direction. There were ultimately three phases of the protocol that were brought to market, before the whole thing was dropped due to lack of market acceptance. In the year 2013, there is still a vibrant market of new, used units & components on eBay, thus ensuring its continued usage by enthusiasts. The MERG series of Technical Bulletins CC1 written when Zero 1 was popular, remain an important source of information and techniques on this system. A MERG kit 71 is still offered which provides replacement parts for Zero 1 system keyboards. Some of the DCC decoders supplied by ZTC Controls Ltd can also be used with the Zero 1 system. A list of compatible decoders appears on the Yahoo site here: | + | An early form of Command Control for model railways, Zero 1 was launched in 1979 and systems incorporating the technique were marketed by Hornby Hobbies and Hammant & Morgan.
