Message-ID: <20003@acf4.NYU.EDU> Date: 4 Nov 89 04:12:00 GMT Organization: New York University Lines: 23 Dear People, I have an ATT6300+ PC runing UNIX V 2.0 ( Ok it isn't the latest but it does its job) . There are some questions that maybe somebody more knowledgable can answer: 1) This PC is running at 6Mhz clock freq: If I install a 10Mhz 286 chip and change the crystal , would it run as usual ?? (maybe it is a dumb question becauise of RAM speed or timing but ...) 2) The soft supports a MSDOS mode and lately I added a 287 coprocessor. Most of the soft takes it except the Norton test that does not find the coprocessor !!! why ? Thanks in advance for any answer or advice Sergio Fanchiotti fanchiot@acf4.nyu.edu
