Hi,
Here's what I get from my Classic II with intvidtest.0.3.4...
I'm booting to single user mode with booter 1.8 and 1.2ALPHA binaries.
After the screen changes over to all white with black text, there are still
2 lines of pixels left over at the very bottom from the finder screen which
was there before.
This is the console output from then on. Scrolling off the top of the
screen seems to work OK - the first line dissapears as the last mrg one is
printed and others scroll up once the panic switch is pressed.

Sizing Memory...Done.

Internal video code really begins here.
The booter thinks video is located at 0xfee09a80
Skipping NuBus video mapping for Classic II
Attempting to grok logical -> physical mapping
Classic II Video (0xfee09a80) internal video at addr0oxfee09a80 (phys
0x9fa80), len 0x8000.
If we got this far then odds are video is working.
Lockups after this point are somebody else's problem!
Done
Bootstrapping the pmap system.
Pmap bootstrapped.

At this point it hangs indefinitely.
I tried pressing the panic switch and this happened:-
Panic Switch: PC is 0x3a46.

And nothing else can be done 'cos the keyboard doesn't work!
So I guess the video is working in the Classic II now - we just need some
ADB (oh and the extra 2 pixel lines would be nice but...) and then it'll
work!
Here's hoping we're that close
