I know you have been referred to the Herne site, but have you looked at
its following page:

This should have most all the information you are seeking.

As to SPORT, I have used it to swap RAMLink (RL) partitions. The RL
system is limited to using only 1541 partitions in CP/M.  However, SPORT
allows an unlimited number of these 1541 partitions.  Also, SPORT will
read the RL real time clock during the boot (from RAMLink) to
automatically set the CP/M operating system clock, etc.  Very versatile.
