Why is SIMH so slow though?
As far as I can understand, one MIPS is roughly one VUPS, correct?
So how come I get 14 VUPS on the same host running SIMH whilst my Hercules install peaks at 180?
Are the architectures that different (obviously they are) or what is it?

There is Alpha support in the development track version of simh.
Is the architecture well enough defined in
publicly available documents? I would guess yes but I don't know for
sure. Are there secret bits that are critical and hard to obtain?
The architecture manual pretty fully documents it.

I'm trying to get the bridge built on OpenBSD 5.1 64-bit but it keep segfaulting. Anyone ever get this working?

Hello!
The key word in my question was 32 bit Linux. That site contains this
line " This implementation will not work on single-core,
hyper-threading, or 32-bit systems. ", which disqualifies my current
Linux system as a target. And I can't qualify the laptop as a target
for the Windows example that Sampsa mentioned, which was also
mentioned on this list a while ago.

Nope. I noticed that Psilo was down, but only now did I recheck and as psilo was back up, I restarted the bridge.
I've restarted mine several times and I'm still not getting anything outside my LAN. :\
Hum. So psilo rebooted again a few hours ago... Restarted the bridge right now.
Working okay now, thanks :)

Sorry, didn't read all the details.
Then I think you are out of luck.

I think they're on final approach over there. He'd better watch his back!
