Current on 86x0
Seems like the recent problems with device detection have been fixed,
and a current build boots. This is nice.
So, here is how my simulated 8650 appears right now:

NetBSD/vax (Puff.BQTnet.SE) (console)
There are a couple of problems right now, that I have not even started
looking at, but maybe someone already have an idea.
The system does not boot if I configure more than 64 Mbyte of memory. If
I configure more, it fails to detect my disk controller, and fails to
come past the initial setup. It asks for the root device, but since it
didn't even detect the controller, of course no possible answer can be
With NetBSD 5.0, the same problem existed, but the limit then was 128
Mbyte. Anything more than that, and failure.
But now it is 64 Mbyte. I think I've also tested the 11/780 emulation,
with the same issue. However, it do work just fine with a 3900, which
I've ran with 512 Mbyte without problems.
(Actually booting the same image.)
Anyone who might know what that is about?
(And of course, if anyone even tries this, they need to fix the boot
block, and then I think there is still some problems with console I/O in
NetBSD with the original code in combination with simh.)
Also, yes, the output here is from a load of code that is not checked
into NetBSD at this time. I'll try and send things in once it's more in
order. A lot of it only makes sense on a real 86x0, since simh does not
emulate the full console system, but the partial emulation is nice as it
is. Unfortunately, some of my code is just on a real 8650, which is in
bits right now because it had to be moved around some.
