Apple learned a lesson with the II when they were charging $320/16KB when the machine first came out and those same chips were available for half that from any number of sources. I doubt that they sold very many "Official" upgrade kits. Even the authorized Apple dealers were selling cheap upgrade chip sets. When Apple brought out the III it originally came with only 96KB. In order to upgrade to 128K you had to get the Apple upgrade kit because the Maximum Memory Size was *BURNED INTO THE ROM*. You could add the chips, but without the ROM, SOS would only talk to 96K. I don't have a Mac and don't know the situation with upgrades. If anyone out there does know how it works, how about letting the rest of us in on it.
