Hi!
Does anybody know how the Video-Ram-contents is changed
depending on the settings of the moderegisters?
mode registers:
M5/1 - Screen select
00000 Screen 1
00001 Screen 0 (WIDTH 40)
00010 Screen 3
00100 Screen 2
01000 Screen 4
01001 Screen 0 (WIDTH 80)
01100 Screen 5
10000 Screen 6
10100 Screen 7
11100 Screen 8
Is there any relation between the _SINGLE_ bits and the vdp-behaviour?
f.e. bit 1 set: maximum 256 colors (unset: 16 colors)
bit 2 set: display 128 bytes per line (unset: 256 bytes)
...
thanx in advance & greetz
wolfgang
