Three CPUs makes me think of the OSI Challenger III - 6502, 6800, and Z-80.

That distinction could earlier go to a PET w/dual floppy - 1 6502 in
the PET, 2 6504s in a 2040/3040/4040 diskette drive.

The Commodore 1541 (standard drive with the C-64) only has one 6502.
You'd need to add a printer or a second disk drive (or a CP/M cart) to
get the whole system up to 3 CPUs.
