[Coco] So does your coco3 do 256 color mode ? Mine does...

Luis,
If you're talking to the OS9 L2 HiRes char set, you just "merge" them wuth the system ie.
merge /dd/sys/stdfonts
This is done externally from the drivers.
All hires fonts are stored in get/put buffers with "special" group and buffer names. The same goes for pointers and patterns.

All the buffers are explained in:
"The OS-9 Level 2 Windowing System" manual
The buffer tables are in chap 3 page 8 (3-8)

You can actually load several fonts and switch between them if you want, but it's tricky programming and playing around with the groups and buffers.
Also, all fonts, patterns and pointers reside "outside" of system and program memory as do almost all graphics oriented buffers. They do not use up program memory but are a major PITA to manipulate if you're not familiar with working with the get/put buffers.

Hope this helps

Still need to make all the drivers, one problem is the charset that
must be loaded from disk. How do I do it in os9 ? Just open a file
into the video driver init ?
