Screen 512*240

Good day, %to! There is such a computer: Profi NGM has an extended screen 512*240 There, through a familiar place, there are mixed, as it were, 2 ordinary Spectrum screens 1 third higher and without attributes, attributes separately for each mask byte in a separate page. Back then in 98-99 I had a thought: why do it through familiar - this greatly slows down the work with such a screen and Bgt on compatibility. These 2 Spectrum ones are much more convenient screen place 1 next to the other from left to right. Then logic the work would be exactly the same as with 2 Spectrum screens with different addresses. If you select 2 pages in the upper memory and link them (yes, although and not only them, but any page) from zero address for reading and recording by latch on some port, then you can strongly increase the information density of the screen, which is exactly the same can be scrolled in 3-4 frames.
