LIST/RUN not working on OSI version

For example,
PRINT "Hello"
work fine, but
10 PRINT "Hello"
RUN
doesn't work.
The line appears to be tokenized and stored to RAMSTART2 correctly,
but LINGET never seems to work.
FNDLIN always seems to look for LINNUM 00 00, even when it's 0A 00.
However, even doing:
00 PRINT "Hello"
RUN
Doesn't work.
I haven't dug further.
