Me neither. I can't do any more until the new tapes come. Otherwise, I finished all the mechanicals tonight. I may have to service some of the electronics or adjust the motor, so I have a few hours of work left but I want to get the new tapes in it and see what I have to work with.
I can tell you this, the keyboard is very simple compared to an M-400. However, the stamped metal frame was bent somewhat and the I had to rebend parts of it to get it back right (again?) I have spent nearly twice as many hours on it as I planned and the amount of time I estimated to get this far was a fantasy. But it is coming along.
