Ooh, I did a new one. Sony MPF-520E E/133

Picture here

  • You can use the jumper on the top of the PCB to select DS0 or DS1
  • Cut the trace between the test point and pin 34, see red line.
  • Desolder the solder blob at SH5 to reveal two jumper pads.
  • Solder a wire from the test point that used to be connected to pin 34 to the left side of SH5, which is connected to pin 2.
  • Solder a wire from pin 34 to a test point near the white flexi ribbon for the ready signal.
  • Optionally bridge the HD detect switch near the diskette opening.
