Replacement memory is quite easy to come buy. A lot more so then the 72 pin variety your so fond of. The process of replacing them is a bit harder, but thats not down to availability, thats down to performance, and eliminating variables that could bring issues to costumers.
But then your not looking for replacement, your looking to change the memory, for some reason or another, trying to prove that 72 pin memories in some arbitrary way is "better".

You do realize that a softcore is a instruction-set running on a CPU other then a 680x0? It's emulating a 680x0.

Years? How do you figure? The softcore is more or less already made, people run everything from 68000 to 68050. The point is that with a flexible design you could simply press a few buttons and go from a compatibility set to another. You need a fast 68000?, load one softcore. Need 68030, load that one. 68060. Well, right now i think you need to develop it first, but yeah, once done, just load that one. The only thing needed is for the FPGA's to drop in price. A lot. It sure wouldn't hurt for faster FPGA's to be available to us either, but for making the equivalent of the current ACA accelerators there are more then enough "oumpf" available today. So the next gen may very well have what it takes for 68040, and so on. It will be a while yet for sure, but it's a lot more likely then barebone accelerators.
