Well, it's the olympics and hence I got some time to spend in front
of the computer instead of in the sofa. :)
So I'm fiddeling with SAM support. Mode 1 GFX and stdio (no ansi)
is fairly complete.
And that the combination of ROM routines, paging of the screen and
SP on the SAM is PITA! :)

I couldn't find them in the copy I had back home - have to check
when I get back. It was 1 AM when I jumped to conclusions... :)

I can send you a disk image of the binary if it's not that I'm just
running an old SimCoupe. Actually, it runs perfectly (though slooowwwly)
in TurboMon. :) Excellent piece of software that! One of my favourites
that one.
