You want to keep the rotational speed at 300RPM, but go to the 96TPI step, and keep the write current at the "360K" level. However, using the "right" drive is always a little easier. Do you need full height or half height? For full height, my favorite is the Tandon TM100-4. (If you run into TM100-4M, set them aside - those are 100TPI instead of 96TPI!) For half height, I like the Shugart/Panasonic 465, although not everyone is happy with those. -- Fred Cisin cisin(a)xenosoft.com XenoSoft http://www.xenosoft.com PO Box 1236 (510) 558-9366 Berkeley, CA 94701-1236

You could try the Mitsubishi 4853 and 4853-1 80track QD drives, as used in the TRS-80 Model 2000. I've seen mention in the past though that the 4853-1 has trouble using DD disks with hubrings. I've also seen mention of the Mitsubishi 504B312U being used as a substitute for these two drives, though I've never been able to verify that model/part number as being valid.
