Who's right? According to Chapter 1 of "Macintosh II and Macintosh SE Cards and Drivers" the correct clock speed for the II is 15.6672 MHz. Coincidentally, this is equal to the pixel clock rate on the older Macs, and twice the clock speed of the 68000 in the older Macs. >P.S. And how about a 25mhz Mac II? Maybe on a NuBus card. -- Stew Rubenstein Cambridge Scientific Computing, Inc. UUCPnet: seismo!harvard!rubenstein CompuServe: 76525,421 Internet: rubenstein@harvard.harvard.edu MCIMail: CSC
