   That will work in a pinch, but it will result in lower-than-normal 
data transfer rates on the RQDX3.  The VS2000/MV2000's disk controller, 
while format compatible with the RQDX controllers, uses a higher sector 
interleave factor which is not required by the it spends a 
good bit of time twiddling its thumbs waiting for the right sector to 
roll around when it could be moving bits.
