This EMU Drumulator is from another famous DJ (his name shall not be mentioned yet). It had a lot of dirty corroed switches. This Unit now has an extended sample memory eprom modification mode. Here are my pics;)

Matsushita? Sorry, no. Get out of here.
Dirty trigger buttons. I cleaned the black ones and replaced the other buttons against new ones.

Last but not least I replaced all LEDs. These looked very, very dim.
