Hello all. I just got a Poly-800 (MKI) for Christmas. It's my first 
real synth and I look forward to recording with it. I've been doing 
some online research and I've discovered that the MKII came with 
internat batteries to keep program and sequencer info stored when 
batteries were being changed or the keyboard was unplugged. I read 
that the MKI did not. However, my MKI keeps all that info without any 
power connection. I opened it today and, sure enough, there was a 
battery in there. I'm pretty sure it was in there from the factory. 
In fact, I'm very sure. How could this be? Did I have a 
misunderstanding (I'm liable to have had one). If someone could get 
back to me on this, I'd appreciate it! Thanks a lot.
