Korg Poly800/EX800 Users

Right. I wish I could make total sense of what you wrote, but your 
basic point seems to be that there is a 3v lithium in all Poly 800s, 
and that it can't power the entire board by itself, correct?  If this 
is what you're trying to say, then I know that.  My point is that it 
seems to be a matter of debate whether the Poly 800 has a memory 
battery or not.  I've been reading up on the issue for the past few 
days now here and from all over the internet.  The most sane 
statements I've seen is that the Poly 800 mk1 went through several 
revisions and at some point a memory battery was added into the 
production units.  The PC board has always had a space for it, but 
not all Poly 800s had the battery installed.

Still, there seems to be folks who are adamant that the Poly 800 mk1 
didn't have a memory battery, while other folks say all Poly 800s 
did.  Neither is clearly true, which is neither here or there to my 
point, which is that the matter is exacerbated by the Poly 800 manual 
with regards to what pages 5 and 40 say.

does NOT have to supply the ENTIRE machine, as the Larger Batts 
DO .....( 'C' or'D' type...can't remember which...the large 
compartment that hold 6 or more -cells ) , then it can be expected to 
last much longer...5 years is typical......If wired differently, The 
whole Korgs drain would wipe it out in less than one hour ! ( 
ridiculous, since you cannot extract 5 volts the entire machine needs 
from 3 v) ...Refer Drawing......
