For those who are building the FSBus system in Australia, the AD Converter on the FSAD3 board is available here : http://www.futurlec.com/ADConv/ADC0838.shtmlhttp://www.futurlec.com/ADConv/ADC0838pr.shtmlIt's only $2.50 AUD. I bought mine from Farnell for $38.00 (Big Difference)I wish someone told me I could find them here at this price.David
