Err, sure, actually the whole text I wrote was not directed only to you, but to anybody who is interested, maybe. Just my two cents, and I quoted you just to refer to a certain context.

Sure, I know. I looked all those IDs up, just to do the readers of this forum a favour, for they are talking about them all the time - and though I am used to talking about "Sawtooths", "Quicksilvers", and such. It doesn?t really matter, though imho this is kind of boring and confusing.

I don?t see the point in searching for a pointer. What would that be good for? If I had always followed Apple?s advice, I?d have bought a new Mac at least once in a period of two years within the past twenty years.
I guess we are just interested in different aspects, for, though I?m prepared to take note of a company?s "official" documentation on their products, I consider third-party information on what customers can actually do with a product to be even more valuable.

You mean "technically" specifying, in a sense that it would be possible to use memory bars which at the release date of a mainboard did not even exist? No, of course Apple would not unnecessarily restrict their (at the time) Power Mac G4 flagship series unless this is technically necessary (or unless Apple profit in other ways from such behaviour, e.g. by using cheaper components). Thus, Apple did not technically prevent their customers from using 4 x 512MB in one of the first PowerMacs, G4 (AGP). Usually, however, the specifications released e.g. in adverts (i.e. what is "officially" supported/featured by a hardware product of the Apple company) do not necessarily correspond to what customers can actually do with their equipment; just see lowendmac.com, to give you an example. I guess that if this would be technically possible (I don?t know) and if a hardware company had created 1GB memory bars for early PowerMac G4 computers, Apple would have neither prevented their customers from memory upgrading nor encouraged them to do so: After all, they want to sell new hardware and software products. Yet, if customers smash their computers as a result from their experiments this is no longer Apple?s problem: Just the usual story.
Thus, I do not really mind about such things apart from what I can possibly do with my computing equipment: I?ll just wait for the next release of MorphOS and see if I can get it running, but to me it will be nothing more but a hobby project.
