(Eric) White & Allcock founded CXG in approx. 1981. The name was later changed to CXG Newcrest Technology Limited. There is very little written about the history of CXG.
Newcrest Technology LTD. may have been the name of the manufacturing company who produced electronic chess computers for CXG White & Allcock in Hong Kong.
It is possible that Newcrest Technology Ltd. was a subdivision of the Australian electronic corporation Newcrest Mining Limited. The ROM chips inside all the CXG computers were marked with the name “NEWCREST”.
CXG Newcrest Technology also sold their chess computers to many other leading suppliers of electronic chess computers. Krypton, Radio Shack and Schneider are just a few examples of the many companies who sold CXG chess computers under their own Brand Names.
CXG for a brief period of time developed and produced chess computers for Fidelity Electronics Inc.
Excalibur Electronics began their operations by selling CXG chess computers under the Excalibur Brand. Excalibur who is based in Hong Kong may still be using today, the original CXG Hong Kong manufacturing resources, technology and chess programs (with some modification) inside most, if not all of their ranges of Electronic Chess Computers.
