Korg Poly800/EX800 Users

Today I opened up the MkI that I bought last night to take a look around.  

Serial number is 038xxx, is that a relatively low/early number?

I can see the spot on the main board where the backup battery would go, so it's a candidate 
for that mod. There is a sticker on the board with a handwritten Z0615084.

The PROM has a sticker marked 830235. I'd like to know if it's the later firmware with the 
sysex update or not.

It's pretty impressive that your kit not only has more features but 
is also better designed.  Is that because of access to more modern 
parts, or are you just better than Korg?

BTW, I still plan on buying the aTomahawk, but when the canadian 
dollar took a nose-dive I got cold feet.  But it's creeping up again 
and I'm more flush with cash so I intend to order it soon.
