Of course, it was full of bugs and had many essential facilities missing, but we beta tested it and wrote reports for one of the Cadsoft developers, Rudi, until it ended up in pretty much the form we have today 25+ years later. Aidan and I bought version one for about £500 and what a winner it turned out to be. Then along came the German company Cadsoft and their revolutionary and cheap product known as Eagle PCB. no solder resist or component legend, typically costing around 300 British pounds after a wait of about 3 weeks. These films were then separated, photographed and sent off to a manufacturer to produce a copper-only prototype, i.e. Once the circuit had been designed and a prototype built and debugged, then a couple of sheets of transparent film were taped together and rolls of red and blue tape used to lay down the pcb tracks. This means that he started out with a pencil and a large piece of paper, surrounded by integrated circuit manufacturers data books and an idea. My friend and one-time business partner has been designing them for around 35 years so he has been through just about every way of laying out a circuit that there is. So, printed circuit boards – or PCBs to most of the electronics COMMUNITY.
