You can do some soldering on the drive itself. this works for most pc floppy drives:
1- Set the unit as DS0, instead of DS1 (pc floppy drive standard)-many have jumpers for this.
2- Route the 34 pin trace to pin 2 and cut it from 34 (do this at the 34pin floppy connector)
3- Join pins 30 & 34.
There is a nice thread on the subject on EAB: http://eab.abime.net/showthread.php?t=30944
On the ones I have done I had to move the DC/RY jumper to RY. Does the joining 30 to 34 replace that step on drives that don't have the DC/RY jumper?
