SPI based interface
My second attempt used an NKC Electronics SPI breakout board for the WIZ module to connect it to a parallel IO port on the BBC Micro. A bit banging SPI routine written in assembler is used for communication. The BoArduino is just there to provide a 5V supply. A short time ago the NRM had the Great Gathering and had six of Sir Nigel Gresley's A4 locomotives (including Mallard, which still has the steam locomotive speed record) all in one place. Two have now left but four still remain.
