WHy would a dealer turn down money to be made? It'll be the dealers option, of course. I will point out that the 128K to 512K upgrade was handled simply by shipping a 512K logic board and swapping it whole. I assume that Apple will handle the ROM upgrade that was as well because it really reduces the chances of error and infant mortality. The ROM's, I believe, are soldered in place, and I suspect few service centers want to be more than boardswappers if they can help it. It is faster, more reliable, and cheaper that way. Now, if Apple sends out a new logic board, and the service center opens your mac and replaces your logic board with their logic board, all of your custom fixes stay on your old logic board. Since your machine is still officially a 128K machine, you get a 128K machine back. Now, since your board is modified, Apple may not accept it back as a core charge from the service center, so they would eat that cost (I think it was $300 for the 512K upgrade). Now, who is making money on this deal? >2. People will bypass the check and get friend's of standard Mac > boards to get a ROM upgrade. Exchange chips in thier own Mac, and > then get the ROM upgrade again and so on and so on.... If you don't mind soldering, great! Assuming, of course, the new logic board doesn't have hardware changed needed for the new ROM, hardware changes for bug fixes, or other things that might make old logic boards incompatible with the new ROMs.... I don't know that this is the case, but I wouldn't ignore the possibility. >3. Worse comes to worse, the hardware hackers who upgraded their Mac > will just copy the new ROM from a friend.

I don't think it'll be as easy as you might expect, but I also expect that the people who are building cheap 512K upgrades will figure out some way of doing ROM upgrades for their customers. People who do their own will have to wait for DDJ or someone to help out, likely. If they can. Please remember in all of this that Apple designed the Mac NOT to be hacked in hardware. So, this isn't a closed door policy on their part, since you weren't supposed to be in the building at all. I don't have figures, but I expect that the number of 'modified' Macs are a rather small minority of total machines. Most new machines being sold are probably 512K, and I expect that most of the 128K machines are either upgraded through Apple (like mine was) or still at 128K. You have to remember that Apple's Macintosh service is built around the board, not the part, so if anything goes wrong they shove a new board in the machine and give it back. The old board goes back to Apple for repair, and eventually ends up in some other Macintosh. People who modify their boards can't expect Apple to fix their board -- Apple isn't set up that way, they don't have knowledge of the changes that have been made, they don't know that the changes aren't causing the problem, and they don't have time to figure it out. What this means, of course, is that if you do things to your machine that you were told not to, like hack the hardware, you are on your own. There will be third party groups that will support you, I'm sure. For a price, of course. Any good group will be able to take hardware modifications from Apple such as ROM's and get them to their customers. Don't expect Apple to do it for you, because their system simply isn't set up that way, and it shouldn't be. When you have 250,000 machines out there, you simply can't survive trying to figure out 10,000 different custom modifications done by people who might or might not be qualified to hold a soldering iron. chuq -- :From the closet of anxieties of: Chuq Von Rospach {cbosgd,fortune,hplabs,ihnp4,seismo}!nsc!chuqui nsc!chuqui@decwrl.ARPA There is nobody as small as those who refuse to accept the success of others.
