When I was having my firms Wang Computer upgraded from one to 10 megs many years ago (for $18K), the tech just flicked an internal switch. He explained that it wasnt efficient to manufacture numerous chips or boards and that all machines were fully featured but software restricted.
Will this be the case with the Marvels, or Will each level have its own firmware and chip?
I am trying a Trial model set to the M90 level and which can be dialed down to the lower levels so clearly they have the technology already. An audi told me that the commercial sets were independant and that you couldnt upgrade down the line by simply paying for a software feature upgade. Would audis even know.?
I dont understand why the manufacturers would not want to be able to exploit an existing client base with upgrades unless the hardware is so cheap that its easier to just swap it out. They could discount upgrades dependant on the remaining life expectancy of the sets.
