thanks for taking some time to read this..

do you need to kno ho wthey work or just the computer part??

if its just the computer part. i cna help you there send me a pm, as the stuff is at home and i'll forgot to post it

If it is just the part about take coin, wait button press, dispense soda, etc. Then a simple state machine will do what you want. I had to design the state machine and then build the entire thing in 512 bytes total while I was in school. Draw a picture, it is much easier.
