And what is data format and screen organisation in mode 256x192x4bit/pixel ? = 24kB videoram.

I find more different layouts of port EFF7, what is standard on Pentagon ?

And what is data format and screen organisation in mode 256x192x4bit/pixel ? = 24kB videoram.

Mode "16 color" per pixel (actually only 15 colors):

Enable: #EFF7 D0=1 - ON, 0 - OFF
Byte structure: 76543210 - IiGRBgrb
Pixel 0, 2, 4, 6 structure: igrb
Pixel 1, 3, 5, 7 structure: IGRB
Used rotate RAM page: pixel 0, 1 - #C000-D7FF, pixel 2, 3 - #4000-57FF, pixel 4, 5 - #E000-F7FF, pixel 6, 7 - #6000-77FF etc.

Characters structure:
#C000 #4000 #E000 #6000
#C100 #4100 #E100 #6100
.................................
#C700 #4700 #E700 #6700

RAM page structure:
(Default / alternative)
CPU 1: page5/7
CPU 3: page4/6

The videomode used Z80 CPU Bus Request mode. The "16 color" videomode is realized in the Pentagon-1024SL v2.2.

I find mode different layouts of port EFF7, what is standard on Pentagon ?

Standard published in the new version emulator UnrealSpeccy 0.36.6 ( http://www.alonecoder.narod.ru/ ).

I can write screen convertor for view SAM COUPE screens (with ZX palette only) in Pentagon-1024SL.
SAM COUPE use too ZX graphic mode 256x192/16 colour /pixel, but screen data is linear and data structure is:
(D7-D0) - I G R B I R G B
D7-D4 = left pixel colour number
D3-D0 = right pixel colour number
SAM COUPE use in all ZX modes colour palette (127 colours)
R G B I output signals is connected to adress bus A0-A3 of SRAM memory and DATA output from memory is 7bit new RGB value (D6-D0: GREEN1,RED1,BLUE1,BRIGHT,GREEN0,RED0,BLUE0).
Pof each of 16 zx colours is possible set any 7bit RGB value.
BMP2SCR PC convertor can convert to SAM COUPE graphic mode 256x192x4bit/pixel with fixed ZX palette. This is easy convert to Pentagons graphic mode...
