I created a small test framework to capture lots of IEEE488 traffic to test 
the XD2031 firmware. You can find lots of traces on github here
https://github.com/fachat/XD2031/blob/master/fwtests/files/f0-1541.frs
Every .frs file is a trace of the corresponding BASIC file with the 
responses for the given drive, here as example f0.lst for the 1541
drive.
Files are self explanatory. I think. :-)

Hope that helps
André
