Roland SDE-1000 80c49 maskROM binary wanted

Hi from Norway!
The mcu (IC21) in my unit is toast (seems to be a common issue lately) and won’t let me dump the content either.
The ROM dump is not available anywhere on the internet or for sale.
If you have said unit and have the tools to dump it, I’m more than interested in the binary file!

Thanks in advance

Mvh
Trond
