You are right - at least mostly.  On the K10 with 81-302 ROM the drive light
and motor does timeout.  Whether this is in ROM or O/S I don't know.
On the KP-2X (81-292), only the drive motor times out.  The light remains on.

Rereading the Micro C manual strongly suggests that you are right.  I don't
now have access to the T'ROM manual, but it likely is the same.  I stand
corrected (and smarter!).
