Casio RZ-1 Demo video

I got an RZ-1 last week and noticed there were no non circuit bent high audio quality demos of the RZ-1 anywhere so here is a quick overview of the sounds and functions of the Casio RZ-1Digital Sampling Rhythm Composer. The RZ-1 was released in 1986 as a competitor to machines like the Korg DDD-1 and Roland TR-707, However its limited functions and low quality sound set meant that it was quickly forgotten, The RZ-1 can be heard on a few early house records and pops up here and there in more recent music. My RZ-1 has a non functioning sampling board and I am looking for schematics and high quality pictures of the circuit board on the plastic side of the casing so if any of you have a fully functional RZ-1 that you are willing to open up and take some pics of I would be very greatful.
