This drive supports Ready signal or Disk Change signal on pin 34 (RY34 or DC34), has a large number of jumpers for various settings, thus (unlike the standard 235HF drive which works in PCs only) this drive can used to replace a 720k drive on older computers such as Amstrad CPC/PCW or Commodore AMIGA.
