SFD-1001: Use of RIOT chips and a copy utility

I've been testing the 6532's I received from China and so far they all 
work except one which is a partial fail. I have been testing them in my 
working SFD-1001 by doing a few load/saves and then running the SFD-1001 
"PERFORMANCE TEST" program off the 1001 Test/Demo Disk. This formats a 
disk, writes some files, reads them, writes and reads from tracks 0 & 
154 and deletes the files.

Originally I was testing 2 chips at a time then the next 2 and so on 
until I got to thinking that maybe the drive never made full use of the 
facilities of both RIOT chips so I went through the whole process again 
but this time i tested, swapped the two RIOT's over and tested again. 
Sure enough, of the 13 chips I have, I have found one that works in 4J 
but not 6J. All the rest work in both positions.

A couple of questions:

Does anyone know the internals sufficiently to tell me what aspects of 
the RIOT functionality is not utilised by the two in the SFD-1001?
Do people think this is a thorough enough test or is there a better 
approach to testing them? (given that the only hardware I have that uses 
them is IEEE drives)
Does anyone have a file copy utility for a PET with daisy chained IEEE 
devices? I want something to copy between devices, not drives in the 
same device.
