Lorraine was the original name for the Amiga computer, named after Dave Morse's wife. The system's basic architecture came together in about 6 to 12 weeks as it was drawn on a whiteboard in the original Santa Clara offices.
Ron Nicholson designed the initial wire wrap motherboards. The first one was wired by Ron himself, starting in April 1983. It had a 68000 and no sockets for the custom chips, as the stacks didn't exist yet.
The second board was codenamed Peace. It had the 68000, 3 sockets for the custom chips and other logic for the system. Peace was followed up in December 1983 with a new board, War. Unlike the first board, Peace and War used wire wrap PCBs made by Twin Industries, also located in Santa Clara. The full systems for each board were known as Respect and Satisfaction.
Wire wrap boards were also made for each of the custom chips before silicon was available. The wiring was done by embroiderers who were contracted to assemble a set of boards for each chip, using a schematic as a reference. The boards were then brought back to Amiga and were debugged by Dave Needle. This was done to verify that each connection was wired correctly. Additional debugging was done using a panel with switches and LEDs dubbed the switch and light box, which was built by Glenn Keller. This connected to Lorraine using the serial port and several probes.
