They are now making accelerator cards which have PC-style processors on them to do the work. You can imagine my suprise at seeing a PowerPC Mac with Windows 95(tm) running on it. The owner explained that a 486DX/100 was doing the job of a PC, while MacOS was (appearently) still running on the PowerPC CPU. -- Kris Kirby UAH Mail UAH CS Home WWW ------------------------------------------- TGIFreeBSD...
