first of all sorry about the spelling.8,16,32 and 64 are very inportant for things like building systems that were design with 8 bit subsystems and manufactures whos systems also were built with 8 bit systems.thaving the newest computer and O.S. to run and monitor the subsystems save them a ton of money not having to replace everything they run on.Oh ever heard of an S.D.card for disk space.I thought you guys were "I.T" techs you should know this.yes?
