Hey there,
I dont contribute much to the group but the only oberheim stuff I have is Perf/X!
Yes they are indeed the same board, I have a Drummer with a bad power supply switch problem that I can't figure out, so I switch out the two roms there into the Systemizer's board when I want to use it (and vice versa)
I had first tried just switching out the one ROM i thought held all the data, but it didn't work. I just guessed and took out the one sitting next to it and switched that and it worked fine.
I've held up the boards for cyclone,drummer, and systemizer and they are all definitely the same board.
