The Dragon Font and lowercase characters
Posted: Mon Aug 04, 2014 7:45 am
In the XRoar sources I found these font files:

font-6847t1.png

I think font-6847.png is the Dragon 32 Font, isn't it?
But why are there lowercase characters? Does the ROM of the MC6847 chip really contains the two bottom character lines and the Dragon 32 ROM simply doesn't use it?
Exit there a way to output these characters?
I have created http://archive.worldofdragon.org/index. ... le=CharMap in the past.
I created the followed screenshot with this simple BASIC test code:

30 POKE 1024+(I*2),I
40 NEXT I
