I understand that – that's because they aren't (generally) rendering; and when
they ARE rendering (320×200 mode, fer instance) they're doing a complete
simulation of what the console would have done anyway, so it all works well. In
our case, we send text (ASCII) to the system as well… then, thru a software
interface, it's converted to bitoids, just like the IBM in graphics mode. We
don't keep anymore around than they do – less, in fact. In graphics mode, they
have the bit patterns, AND they have the text (in the BIOS map) so they can
mess with it – and we can't. They don't try and read the bitmap, because they
don't _have_ to – someone thought about it (probably one of the few things they
_ever_ thought about) and decided it was a lot more reasonable to keep a text
map around for after-the-fact use. And again, I say – they were right. –Ben–
