ok well .... the format changed in 2007 By the way .. just thought ill tell u ... and the answers to ur questions

a) these are the devices ... temp. - heater time - timer

b) data is been inputted and passes through an ADC device used to convert to digital ... it then passes through the microprocessor chip used to compare the stored data with the data that has just been set .... when the data has been compared it then pases through an DAC to convert back to analogue and then it triggers an alarm or a beep sound indicating the food is ready :D
