It is possible that trying to boot off an archaic system disk may crash the computer. In this case all you have to do is restart the Mac and hold the mouse button down until the disk ejects. You should never have to use a paper clip or a screwdriver(!) to get a disk out of your Macintosh. Greg Herlihy gregh@inmet.inmet.com

Along the lines of the trick of holding down the mouse button on reboot to force the ejection of a faulty boot disk in the disk drive, has anyone got a nifty compilation of OS level keyboard/mouse shortcuts? Things like this mouse trick, the command F and command K business to print postscript to a file, the key combo needed to rebuild the desktop on bootup, etc. _______________________________________________________________________________ Dan Peterka S-CUBED 3398 Carmel Mtn Rd. dan@scubed.scubed.com (619) 587-8338 San Diego, CA 92121 _______________________________________________________________________________

I hear the IIci's 68882 is pretty quick, especially at transcendental functions. It is conceivable that in some applications, it may be 1000 times faster. Also, the '386 box might be thrashing the hard disk due to a 1Mb MSDOS memory limitation, while the IIci may have 8Mb of RAM. This could give a speedup factor > 1000 very easily.
