Let's not forget the Scottish company Clydesdale who I worked for, for over 18 years. They were the importers for NEC and Cap10. Clydesdale supplied the independent retailers and others from the Basingstoke Depot, ran by John Nisbet.
I still have my course info on the NEC PVC-740 Beta video recorder. I also was on courses for the NEC Authentic audio systems.
