personal computer by Apple

Second Class Macs are Apple’s somewhat compromised hardware designs. For the most part, they’re not really bad – simply designs that didn’t meet their full potential. Take the 16-bit motherboard of the LC , replace the 68020 CPU with a 68030, strip out the expansion slot, and put it into a Classic case – and you have another Second Class Mac.

Problems the Classic II (a.k.a. Performa 200) shares with the LC and LC II are a 32-bit CPU hobbled by a 16-bit data bus and a 10 MB RAM ceiling.

Apple tried to position the Classic II as a replacement for the venerable SE/30 . However, the 16-bit data path gives it about 60% as much horsepower as the SE/30. On top of that, the Classic II has a 10 MB RAM ceiling, while the SE/30 can handle 128 MB. Finally, the SE/30 has a PDS expansion slot, but the Classic II has no expansion slot.
