Hi All,
I seem to have reached a dilemma in my own homebrew XT project, on the issue of graphics adapter emulation. Firmware limitations have forced me to settle on two main options. These are:
Low-res Tandy/VGA Mode 13h support
80x25 color text (CGA)
160x200 16-color
320x200 4-color
620x200 2-color mode
320x200 16-color mode (PCJr/Tandy1000)
320x200 256-color mode (MCGA/VGA)
EGA 128K compatible support
80x25 color text (CGA)
160x200 16-color
320x200 4-color
620x200 2-color
320x200 16-color (EGA)
640x200 16-color
640x350 16-color interlaced
640x400 16-color interlaced
Tandy/VGA combination is pretty much ready now, while EGA route might take a little longer to achieve good compatibility. It's a pretty tough call for me to make, hence my poll request. Thanks in advance.
Happy voting!
