You can just short circuit it to pin 33 but it's better to cut the track on the drive to pin 34 first. This will normally work on most drives but some drives will go off-line if there is no response on the disk change signal (disk change reset) It also depends on the software on your MSX , some really use the ready signal on pin 34. On a NMS8250 it works. It's also advisable to close the HD switch permanently to avoid real problems when using hd diskettes (you will keep some small problems) If the motor will not spin or spins permanently look for a jumper called Mon and change it, but this is only on very old drives.
