Brian,

there is no later firmware that supports SYSEX in the Poly-800.

The only thing that was out there (until the HAWK-800 came along) was the Korg MDK ROM kit.

You can still find them, but they are very rare and they are an absolute dog to install. Cut tracks everywhere, jumpers all over the place. Not a pretty site and easy to screw up.

If you want full SYSEX support, buy my kit!

Mike.

Subject: [korgpolyex] Trying to date my MkI

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.
