New and Rumored Machines -- Power Computing was showing off the PowerCurve 601/120 at Macworld, a desktop Mac with three PCI slots and a 120 MHz 601 processor on a CPU daughter card. Expected to be shipping in a month or two, the PowerCurves will be available in desktop and low-profile cases, have options for NuBus slots (once Power Computing's Stargate technology is available), and offer a lot of horsepower for just a bit more than Apple's current prices for the Power Mac 7200 series. Rumors were also circulating about a Performa-branded new mini-tower design from Apple codenamed InstaTower to be priced around $2,000, and a forthcoming PowerBook, codenamed Epic, that sports a full-sized CD-ROM drive.
