The Sharp X68000 managed 768x512 in glorious 16-bit colour back in 1987. Japan liked high resolution displays, since Japanese is hard to read at 320x200
Yeah, same feeling with NEC PC6001 series...
3 MArks :
1st is like speccy.
2nd is like Amstrad CPC (Mode0 and mode1 resolutions).
3rd is like having even twice more horizontal resolution (twice the bpp, so actually 320x200x16 and 640x200x4...)...
I wish the Amstrad PLUS could into twice bpp rate with the same video modes... would be quite perfect yet need a lot more RAM/VRAM too and some faster Data channeling.
I'd crave for a 160x200x256 mode...
Back to Apple.The
AppleII series got a lot of clones I guess.
I couldn't find proper informations on the video modes and colours (isthere really that kind of stuff ?).
To me AppleII is always in monocolour monitor...
Is it ?
The colour was mostly using the compsite monitor trick I guess (a common feature in pre-1984 usa... like CGA...)
Apple IIgs was quite a 16bit version thought, and I like the almost AmstradPLUS way to deal with more than 16 colours...
You have like raster attributes mode.
So 16 colours per scanline, and a fast way to process for this... like an attribute map.
On Amstrad PLUS you can get quite that thing but sadly even the improved Rasters are not as good and may be a bit heavier if over-exploited (I guess, is it ?).
Apple IIc was a good compact machine, said to be "portable"... well more like "transportable" indeed.
It's design in 1984 predates the Atari St/Amiga 500/thomsonMO6/Amstrad PC20/Amstrad PLUS designs...
Also Apple released some "AppleII on a card" : extension cards to put on a Mac to get a Hardware emulation...
I wish amstrazd did the same with CPC and PCW for its PC..
A proper "CPCW" card could be great and could even be used as video and sound card at the time...
Video : you get some modes better than CGA.
sound : you get better than the standard buzzer/beeper (yeah, just a mundane AY, still as good as on Atari ST...)
Technically it would be a sound and video card with it's own Co-CPU (a Z80) and its own RAM (like 64K or even 128K)...
Many tricks are potentially conceivable for this...well... on the paper.
This on a PC1512 (or a PC20...) could definitly pull a good "Gaming machine" potential for the time (1986-1987...).
There was an extention on CPC to turn it into a PC... but it was quite the reversed concept....
Concerning design : Snow White design language.
