So here is the sad and embarrassing story... It began at Christmastime when my father-in-law decided to give me two CPU upgrades and a bunch of memory. To make a very long and sad story shorter, the PIII 850 MHz CPU I got is not compatible with my motherboard (an Intel SE2, specifically 720-series). So, I have a PIII 850 I can't use and was wondering if anyone would like to swap a PIII 550 or 600 MHz for the PIII 850. Yes, you read correctly, I am willing to trade down! If anyone is interested in the details, the following URL will give you all you want to know: http://developer.intel.com/design/motherbd/se2/se2_proc.htm. You will note the listing of motherboard revisions in the third column of the chart. You will also note that the 600 MHz PIII is the fastest chip my board can support, it not being a 754-series board. Thanks, Steve P.S., don't let Doug know about this... ;-)
