Quite right. I should have been more clear about both rather than use the
term "emulator" which I already knew was pretty loaded with expectations.
However, my point was only that if Executor could do it, so could someone
like Nutek. However, from reading about the hardware, it sounds like it
had an actual '030 in there.

Well, WINE is probably a closer analog to Executor than ReactOS. However,
again the point wasn't to define "emulation" but to say that
re-implementing an OS isn't easy and has a spotty history of results.
That's all. I agree with you that it's not impossible to do right. Just

I understand. I've used many such API-rigs myself under both NetBSD and

I'm not sure what you're referring to here: binary emulation, POSIX
compliance, Single UNIX Specification, iBCS emulation, etc... Personally,
I've seen NetBSD "emulate" (for lack of a better term) a lot more
commercial UNIX systems than Linux ever has. I've also had a lot more luck
cross-compiling to other OSs which has some overlap with the whole
API-emulation topic. However, in some of those cases you need to fetch
libraries from the original dist to make it work right and that's probably
"cheating" to most people who want to get froggy about the "emulation"

It sounds interesting. I'm familiar with Firebee and MiNT, though this
sounds a tad different. I'm not expert on STs, but I think they are neat.
I'll have to check it out.
