Indeed. My other wish is that someone far brighter than I will someday
develop a MIPS emulator capable of emulating IRIX. The odds of that aren't
great since untangling the ROM would be a real PITA.

Yes, and don't forget the NeXT platform which had "quad-fat binaries"
capable of running on 4 (!) platforms at once. It might have been a little
top heavy and impractical at times, but it was soooo cool to me. I'm sure
you remember "Rosetta" too. IRIX on x86 would be heresy to some, but I'd
welcome it *especially* if it could dynamically translate MIPS ECOFF
binaries, and run legacy IRIX software. I know the lawyers would never let
any of that happen, but a man needs to have some dreams. :-)

I see your point and I agree.

An oil-tanker sized boat. Yep. Unless of course you could keep everything
pin compatible etc... which is even harder. "We're gonna need a bigger

Well, I appreciate that fact that anyone is doing anything! If I ever
meet "Lotharek" I'm definitely buying him a round. I get excited just
looking at some old gear that someone's cleaned up nicely or polished the
face panels on. I'd probably die in an apoplectic fit if I ever saw an ad
for an SGI accel board. If I ever make someone mad, they could totally get
back at me by handing me a fake flyer for "Press release: Acme Inc
releases SGI MIPS accelerator board based off high speed GPU". When I
found out it was bogus I'd go jump off the roof. Joking aside, I do see
your point about restoring vs enhancing, and it's well taken.

Amen brother, I was just wishing out loud. I needed someone to bring me back
