Ah! this debate brings me back to my Color Computer days! For those that don't know the CoCo had a 6809 processor that had a 8 bit Data bus and a 16 bit Address bus, so everyone debated 8 or 16? I am sure those with the Dragon know what I am talking about as the dragon was essentially the same computer as the CoCo.
Yes, its off topic...
Reminds me of the Ti-994's & TG-16 systems.
But I've always considered an Amiga running 16-bit ram to be a 16-bit computer.
Amiga's with 32-bit ram and NO 16-bit ram is a 32-bit computer. Mixture of both types
could just as well be considered 24-bit. LOL! And speed wise, you all know what I am
talking about.
