As I've just ordered a couple of QuadDoubler /edit/ NewerTech Quadra Overdrive / accelerators (/edit/ one 33MHz 650 compatible Overdrive Plus with 128kB cache and one cacheless 25MHz 605 version, both runnning 50MHz full '040s/), I'm casting about for the bestest possible Quadra motherboard to mount them in.
Here are various assorted and somewhat rambling thoughts to that end.
Looking at the specs on LEM, it seems the 650 and the 800 are identical. Same CPU, same benchmarks, exact same paragraph about Q950-beating interleaved RAM and faster SCSI.
And given that the one is a drop-in replacement for the other, and this:
Is 10% speedup worth giving up the extra 2 Nubus slots and twin SCSI buses in a 950
Is there any way of creating a SCSI RAID on a 68k machine?
And if I was willing to trade in Nubus slots for IDE, how would either of these compare with a 630, which also sports a 33MHz CPU?
I'm leaving aside space issues here, as it's likely the final monster will end up in a custom case of some kind. I'm also not averse to a bit of soldering and adapter fabrication to solve any connector clearance issues.
The 630 'board has the advantage of possibly fitting into a SE/classic shell. It and the 650 also share the substantial advantage of being in my possession, and not requiring purchase and trans-Atlantic shipping at great expense.
Another consideration - 630 DOS CPU card, with the QuadDoubler on top of that ...
Finally, compatibility with some form of Unix would be a plus.

... are they in fact the exact same motherboard?it really detected a Q650 mobo although it was a Q800 one.
