Paul,  am pretty sure the 9877 was just 4 9825 tape drives and their 4 discrete controller boards out of the 9825 set to individual peripheral address, do remember seeing them from time to time in production area.

Regarding the 9875 dual tape drive, this was known by the internal project name Spinner, and as best remember was a BPC alone with a pair of TACO controlling the two tape drives.

Turns out the source code for the 9875 has been preserved and is available to review if there were interest,  Dyke
