Thank you ;)

If you happen to have an EPROM programmer then can you read out V3.0 and share it here? I have 3.1 which I will be sharing in a day or two, so you will be able to update your machine if you have a way to burn your own EPROM.

Roland JX-8P Operating System EPROM firmware binary v3.1 (for newer JX8P revisions only)

Also, version 2.1 is available at the world-famous DBWBP.com synth firmware archive. That dump includes ROM B, should anyone be looking for it. Again, most new revision boards use a mask ROM for this, so it is basically non-replaceable (but should never need to be replaced anyway).

If anyone has v2.3, please do post it. It's the last firmware of significance for the JX-8P that needs to be dumped.
