Yes, I'm right. According to the Apple //c
Reference Manual, there are 8 blocks that
run this way:

$400-$477 leaving $478-$47F
$480-$4F7 leaving $4F8-$4FF
$500-$577 leaving $578-$57F
$580-$5F7 leaving $5F8-$5FF
$600-$677 leaving $678-$67F
$680-$6F7 leaving $6F8-$6FF
$700-$777 leaving $778-$77F
$780-$7F7 leaving $7F8-$7FF

It's not much more to code it,
just a few modifications.
