This permitted implementation on relatively slow CPUs (video encoded in Cinepak will usually play fine even on a 25 MHz Motorola 68030, consoles like the Sega CD usually used even slower CPUs, e.g. a 12.5 MHz 68000), but tended to result in blocky artifacting at low bitrates, which explained the criticism levelled at the FMV-based video games.
Sharing the same compact case design with three expansion slots, the IIci improved upon the IIcx's 16 MHz Motorola 68030 CPU and 68882 FPU, replacing them with 25 MHz versions of these chips.
The 40 MHz speed referred to the main logic board clock (the bus), the Motorola 68030 CPU, and the computer's Motorola 68882 FPU.
It replaced the 16 MHz Motorola 68020 CPU and 68881 FPU of the II with a 68030 CPU and 68882 FPU (running at the same clock speed); and the 800 KB floppy drive with the 1.44 MB SuperDrive (in fact, it was the first Mac to have one).
The Motorola 68030 ("sixty-eight-oh-thirty") is a 32-bit microprocessor in Motorola's 68000 family.

The 68030 was used in many models of the Apple Macintosh II and Commodore Amiga series of personal computers, NeXT Cube, Sun Microsystems Sun 3/80 desktop workstation (a member of the "sun3x" architecture, where the earlier "sun3" used a 68020), later Alpha Microsystems multiuser systems, and some descendants of the Atari ST line such as the Atari TT and the Atari Falcon.
