John, In addition, there are differences in the MCM within the boxes. Check out the following PDF, starting at page 18 for the answers to your question.

The "2Cx" models are referred to as the "turbo" models. As an example, from Cheryl's CPU chart, the model 101 was rated at 216 average MIPS, the 1C1 was 225 MIPS, and the 2C1 was 275 MIPS.

At <http://www-03.ibm.com/servers/eserver/zseries/z900/glance.html> I see this: Hardware models General purpose models 101-109, 110-116, 210-216 Capacity models 1C1-1C9, 2C1-2C9 However, I don't see a definition of "Capacity models"; nor do I see anything that would intuitively distinguish between a "general purpose model" and a "capacity model", other than the C in the model number. Can somebody give me a clue what "capacity model" means?
