Why glitches? or you can't do anything except glitches
writing? :v2_lol;
Actually; I meant examples of output to the professional screen, how it turns on...

Hello, drbars
512x240 (can be color - attribute byte per graphics byte and black and white - color is specified
border). The screen is divided not into 3 thirds, but into 4 quarters. those. 64 64 64 and 48
lines respectively. the mode is similar to the Pentagon 512x192, but here firstly
The columns are swapped, i.e. at addresses #4000-#5fff odd, and at
#6000-#7fff even. pixels are not square, but width = 7/12 height. projected
banks are not 5 and 7 as on the standard Spectrum, but 4 and 6 and the corresponding ones (if
color mode) banks with attributes in the upper memory 3A and 38 like (on pro
maximum 1mb - 3F cans).
on the board of the latest version (v5.x) there are mskh for a palette of 256 colors, on the screen
Moreover, without multicolor there are still 16 colors.
also in extended screen mode, the flash bit of each color byte controls
separately with the brightness of ink (or paper), and bright with the brightness of paper (or ink).
The mode is enabled by setting bit 7 in the #DFFD port. however not recommended
abuse mode switching - failures are possible due to changing all
scans and video controller access to memory

Hello, rasmer

Hello, SAM style
Yes, judging by the description, working with such a screen is quite slow. Unless
build a table) And as I understand it, you can’t really play around with stack commands...
Our iron workers don’t learn anything...
I wonder if people coded demos/games for this video mode? Maybe someone knows
where to download? :)
Hello, drbars
The most beautiful thing I have ever seen is the solitaire game Klondike. :)
