do you know, whether your "synth guru" reprogrammed the original
eprom chip, or whether he replaced the chip with NOS?

So now I'm trying to get the old JL Cooper midi interface to
work. It arrived outside of the synth with no cover on the eprom
window. I assume it had been exposed for a few years so suspect
this could be a cause of the interface not working. It is a Rev
1.1 board. A long shot I know, but does anyone have a bin file
for the JL Cooper Obxa midi board?

Thanks in advance and also thanks for all the prior help!
