Q: Are extended graphics modes standard?

If you can see me, it means you managed to break through the police
cordons ;)
Sorry for the off-topic.

Now a question for dear All.

And there are STANDARDS on the Spectrum for extended graphs. modes.
Or at least in the FAQ something to summarize everything that has already been done in terms of extension. graphics.
And how would you feel about the proposal to introduce the following:
256x192x4 bits of gray (for video), 512x384 attr. - just a standard screen quadruple in area, IMHO useful for games with a large card
And yet, I still have the crazy idea of connecting an SVGA (VGA) monitor and
something else, and therefore maybe someone can give me a diagram of the Pentagon (preferably
under PCAD), with perhaps the most detailed description of it + an SD diagram with a description.
I’ll just say right away: it’s not a fact that any of this The idea will work out, but
I still want to try.

And really no one will send ZXCPM.ZIP? I would like to make hardware emulation of VT52 for CP/M.

There are three ways to solve the problem:
1) Complex: You remake the SVGA to the required frequencies.
2) Simple: you put out an ad, a cool electronics engineer comes and does it.
3) Serious: you remake the computer’s video system. On the Spectrum, everything is on one
quartz tied... And this is not good...
