A quick note on the beeps (no, I didn't think it was funny either!) - I
think I'm going to use the 'ole Adlib card to emulate the BBC sound
chips. I haven't actually done any Adlib programming but I have looked at
the documentation a bit and seeing as it is the same sort of thing as the
BBC sound chip (although more advanced) I don't see why we can't convert
BBC envelope commands into Adlib ones by simplifying them a bit and
rounding everything to the right ranges. Any ideas?
I'm heartily relieved to find that I don't have to do much to get BASIC
running; I might have a quick shot tonight. I presumably have to emulate
screen memory, though? I am assuming (a bit naive on these bits, I'm
afraid) that the OS writes to screen memory directly; there was no
hyper-special custom chip to do text displaying? Actually, that sounds
like rather a dumb idea and I wish I'd never suggested it. Just ignore me...
