----------------------------Original message---------------------------- Regarding CPU speed only, Debbie Lords is correct according to the people who build computers on campus here. The 66 Mhz machines are actually running 2 33 Mhz chips, and the 50 Mhz machines are running a single 50 Mhz chip. Software developers could take advantage of the double chips, but most don't, so software ends up running at the speed of the single chip--33 or 50 Mhz-- depending on your machine. The rest of the stuff that Sonny (hey, who let you on our list, you tropical ag person, you--Oops, Hi Sonny...) was describing will certainly affect the overall speed of data processing. ...and I'll raise you .02.
