There's even more, see

"$E57C-$E599: (compute screen address)" looks suspicious. Yesterday I
found out that putchar overwrites I/O memory beyond the color RAM.
Possibly it's used out of screen bounds accidently, I'm still searching
for the issue. And this wouldn't explain why it doesn't work with 02.
