All 8-bit Commodore disk drives have CPUs, period, IEEE or no. Some older
drives have two, one for "IP" to accept commands over the Commodore serial
bus and one to act as FDC. 1541s and later drives have "schizophrenic" CPUs
that alternately switch between IP and FDC modes on interrupts. MFM-capable
drives like 157xs and 1581s have a special FDC (usually WD-1770 or 1772-type
controllers).
