GFX mode 512x192

And it all started on 20-Jul-00 at 21:12:00, when Ivan Mak
talked with Dmitry Naboka about GFX mode 512x192

GK>>> Tell me if there is a subzh in color, and if so, is it compatible
GK>>> is it compatible with the old one device?
DN>> afaik, no. Yes, and such a regime will not work, IMHO.
IM> It will. And even in color (Sprinter has long had 640x256x16 and
IM> 320x256x256).

So on a regular spectrum you will have to supply an additional
line for it, won’t you? Well, or static (by the way, you can use the cache)

Well, yes. Just like in Sprinter. :-)
When calculating how much memory is needed and at what frequency, you just need to proceed from the fact that for the 320x256 256 colors mode you need to remove 7 million bytes per second. That is,
If there is only one sim, then the processor will have no time left, which means that for such a mode
you need at least 2 sims in parallel... And the same for the mode of 640 points in
lines and 16 colors.

The protoss escaped. The Zerlings took off. It's time for me to call it a day. Ivan.
