[Coco] Supercomm fails to load on NitrOS9 lvl 2 on my CoCo 3 with 128K, and a couple of other questions?

 Curtis, it's all there (and more) :-)
The graphics text scrolls are much faster than they used to be. The IBM extended font is in the sys dir and actually looks pretty good. I have about 15 different fonts. I used to have more on my old system, but apparently that disk wouldn't read. I had a homemade font editor in basic09 that I used to create about 30 or 40 fonts of all kinds, mostly just decorative stuff to use on graphics.

And Dave, using a graphics screen on a 25mhz CocoPFGA, um well, that's going to be faster than using a text screen on a Coco. I run Vcc at about 78mhz most of the time (for compiling speed) and full graphics screen updates are just about instantanious. But yes, a 1.78mhz Coco 3 is still a little slow, even with the new speedups in NOS9. But it's still much faster than a 51 column PMODE4 screen was on a Coco2, which I used for a couple of years until the Coco3 came out.

Nitros9 (at least, as of version 2.10 that I last worked on) had support for 224
character fonts in graphics modes (and 25 lines), and I did an IBM extended
character set font for it as well, specifically for that reason (Alan Dekok also
had sped up the printing of graphic fonts drastically from the original). I used
it with some simple terminal programs to see those characters on BBS's. The one
issue it had was that in order to get 80 columns, you could only go up to a 4
color screen, so not all colours were supported (to be honest, I usually only
used it in 2 color mode, as it was a little faster). 
I also had disassembled
Supercomm, and had started optimizing the serial read routines to speed it up,
but I honestly don't remember if I completely finished that, or released that to
the public.
