Technically FM on 8" (250k) and FM on 5.25" (125k) are different but only in 
transfer rate.  If it handles 3740 as well as IBM 360K then it should handle 
most CP/M and all CDOS formats.

The only real issues are either differences in different soft-sectored 
controllers (Western Digital based chips have some formats that the 765 
based chips can't handle but are rarely used) or the basic ability to handle 
FM (as in 3740 format).
