If I can't figure the controllers out I'm
going to be looking for a
similar drive. I suspect the trusty ST-225 works - the geometry is the
same.
Michael, my info is from some 20-odd years ago, but as far as I
remember, I formatted a ST225 and a ST238R (in MFM, so 20MB) in this
controller. I had one with a WD drive in my first XT :)
