To: outnews#ext.nn.comp.sys.ibm.pc@andrew.cmu.edu, martyl@rocksvax.UUCP (Marty Leisner) In-Reply-To: <868@rocksvax.UUCP> in response to a few questions: 1) I think the only way to tell is to look at the model number on the back of the unit or to look at the BIOS. This is not foolproof as many people install various "speed-up" devices to make the 6 MHz machine act like 8 MHz machines. 2) The 8 bit RAM will perform about 4 times slower for word access and about 2 times slower for byte access. 3) Persistence is dependent on the type of phospor used in the monitor. Sometimes playing with the constrast and brightness controls will help a bit but in general, the type of phospor is the critical factor. Best regards, Paul
