I have this module. It will boot (slowly), but very annoying to play because it won't retain any of its settings when powered off. The on-board backup battery has failed, and unfortunately it's soldered to the motherboard. I need a good electronics tech to help me replace the battery.

I fooled around with it enough to say that the sounds and styles aren't as good as TOTL products from the big 3 made in the last decade. Compared to the BK-7m or Ketron SD40, it's big and bulky. But I like the chord fingering options, and the feature set is very complete. GEM had some clever innovations, it's a shame they didn't survive. Overall i think this module is very comparable to a Ketron SD3.

I think storage is still floppy disk. There are aftermarket kits to convert to USB but they are expensive, and who knows if they really work? If I ever get the battery replaced on mine, that would be the next decision.
