Good to know German Post did not manage to fubar the parcel.. ;)

The idea of ripping a ROM image came to my mind quite some time ago,
unfortunately the eprom is soldered in quite good. I tried reading the
content in-circuit with a signal analyzer, but the surrounding logic
attached to the eprom made the results worthless. So, apart from
de-soldering the eprom, there is little chance. Perhaps the firmware
can be controlled to dump the data on the midi port, but I doubt that.

On the other hand.. now that you rightfully posess an original hardware
MT-32, wouldn't it be allowed to get hold of the rom images from the
internet somehow? They _are_ available.. somewhere.

If not, well, I trust in you Max to handle the soldering iron well ;)
