...if anyone will know, it will be one of you.
Using one of the accelerator boards as a template, would it be too
difficult to design a 68060 accelerator board for a 68040 NeXT? I guess a
big part of this question is: how different is the architecture of the
68060 to that of the 68040?
I think the real problem is that the OS wouldn't like the CPU. If you want
a faster NeXT system you're probably better off buying a Semi modern PC with
a nicely outfited Matrox Millenium II graphics card (IIRC, that's the best
card OPENSTEP 4.2 supports). This would also allow you to have 100Mbit
ethernet (the lack of which was why I gave away my slab).
