This is not uncommon.
H89 had two, one for the terminal and the other was the processor for
the computer.
My NS*Horizon had two when I added the Teletek HDC(hard disk) as that
has a local z80. When I added a smart FDC of my own design and later
smart printer spooler and other IO with local cpu the nuber fo cpus grew.
The Compupro system can easily have three, ZPB, Their mux board and
any of the hard disk controllers. I have one that has 68000, 8085 and
Z80 (maincpu, mux and Disk3).
It's something that isn't unusual as it would seem.
Hi
The polymorphic 8813 had two processors when it used the
double density disk.
The main processor was still the 8080 while the controller
was run by Z80.
To make it more interresting, the double densities disk
were still hard sectored!
