This let you run problems on it that would previously have required a mainframe, albeit slowly. As for what makes a mini/micro/mainframe... if you can hold the CPU in one hand (1 to a few chips) it's a micro. In two hands (1 to a few boards) it's a mini. Otherwise it's a mainframe. And if it's what you buy for no holds barred performance (extreme inflexibility in demand curve), it's a super. -- Peter da Silva. `-_-' +1 713 274 5180. 'U` peter@ferranti.com
