For whatever reasons, 80287 chip clock speed is dependant on the specific manufacturer's design. The general guide is 2/3 of the 80286 clock speed, but it's certainly not a rule. VICTOR is also certainly not the only AT Class computer that does that. -Sean -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Sean_Cox@mts.rpi.edu \ "Life is a tragedy for those who feel, and a userGDQT@RPITSMTS.BITNET > comedy for those who think." -Jean de LaBruyere skeeve@pawl.rpi.edu / "F*ck 'em if they can't take a joke." - John Cox
