well thats simple enough, anything with a record button on it can sample,
my sampler of choice is cooledit, or audition as its called these days.
put a 70s movie or record in the cd drive and record whatever bit it is you may want, and save it down on your harddrive.
sampling isnt very difficult at all, specially with the internet at your fingertips.
but you got the idea down, break, bassline and a stab, just make the same thing with your own components.
