it won't change the fact that nobody will ever be building a viable desktop motherboard usable by OS4 ever again! This is why it's **DEAD** for all purposes of interest to Amiga users!
That is a bold statement.
Lets see, from the time of the commodore demise, we have seen the AmigaOne, Pesesos, a bunch of SAMS, and now finally the X1000. (I never bought any of them, because they cost associated with them in my opinion is just too much money for the luxury of running OS4.X... but that's not the point...)
So, you are seriously saying the x1000 is the LAST OS4 compatible PPC motherboard that will ever be produced? I did not think the x1000 was ever going to be produced, but here it is, all 3000 dollars of it

On a completely different front, we the complete recreation of the Amiga chipset in the fpgarcade and the 68060 expansion board is in prototype stage from my understanding.
Are you saying that they (the people behind the fpgarcade) will NEVER make an expansion board that has a PPC processor in addition to or in place of the 68060? It would then be a PPC motherboard running OS4 classic, right?
How about this. If a new OS4 compatible motherboard is produced, and assuming you have two working kidneys at that time, why not make a commitment to donate one (to somebody on a waiting list) in honor of Jay Miner?
Sounds like you have nothing to worry about...
