The Ampro can read 48TPI disks on 96TPI drives, and since Joe Wright wrote
the BIOS for the SB180 and is/was heavily involved in the Ampro software I
suspect the SB180 will also support this capability. Another solution is 
to spend the $20 for a single sided 48TPI drive and use it as a spare for
compatibility purposes.
