hi Alain there a way for Mach II owners to upgrade themselves their computer to >the Mach III ? many people try to modify the chess computers by adding more ram or switching the processor or over clocking with a higher Mhz speed this is not a problem only for Fidelity computers but many computers >for example, by getting from Fidelity Electronics the instructions as well as a >new ROM (and may be RAMs too) and do the upgrade at home. no.Fidelity would not allow someone to preform their own upgrade .you had to send in a computer for it to be Factory authorized for the upgrade i doubt very highly that Fidelity would upgrade the Mach II to the III because several things were different from the II TO THE III(Program was improved ,and the clock speed increased) i have never heard of a Factory Authorized upgrade from II TO III > > >Additional question : >in an old answer, our guru Steve wrote : >"2)Fidelity also preformed factory authorized upgrades from the Mach III to the >Mach IV retaining the 6098 model number. " >Is there a way to distinguish such an upgraded Mach III->IV from an true Mach >III ? I am not sure i understand the question? a True Mach IV will carry a 6110 model number if you are asking how does one determine exactly if they really have a Mach III OR a Mach IV then test your computer the Mach IV was perhaps 75-80 Elo stronger then the Mach III if you test both of the computers using the standard BT2630 or BT 2450 Suite of test positions you will get very different solve times for the two computers follow this link and test your Mach III many computers have been tested with the solve times recorded http://www.schachcomputer.at/bt2630.htm Best Steve
