Mac POrtable system

About a year ago, I got a Mac Portable, which I really like. Back then, unfortunately, I had the tendency to upgrade everything to the most recent version, so I installed System 7.0.1 on it. Since then, I've wanted to play with an earlier OS to save RAM. I will eventually download OS 6.0.5, but for now, I just picked up WordPerfect 1.0.2, which has OS 4.2 on the disks. FInally, my question: when I try to boot off the disk, it freezes during the "Welcome to Macintosh" screen. It shows up fine when I boot of the hard drive, and Norton Disk Doctor doesn't show any problems. Ideas? In general, what is the earliest version the portable can run? By the way, it looks like I have all the needed files on the disk. PS, what should I pay for an ImageWriter II? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
