PMODE 4 Video Memory
PMODE 4 Video Memory
Is it possible to setup a PMODE4 Hires screen and poke a value into screen memory? I tried it and it didn't seem to work. I tried poking the value 170 into 1536 to 1536+512 and Step 8 hoping to get a bit pattern of 10101010 on the screen but it never appeared. I know I am missing something but I am very rusty with Dragon/CoCo BASIC and the graphics screens.

If you're running with a disk system (or emulating one), all the "normal" video addresses move up by 1536 bytes, so if you're setting PMODE4,1 then try POKEing from 3072 on.

Does this apply to CoCo2's as well?
