No.  Once upon a time you could buy an LJ -> LJ+ upgrade, but that was a
brain transplant that replaced the entire board.  The LJ board isn't designed
to be field-upgradeable, and there is also the little problem that there is
no documentation on it.  (The LJ/LJ+ service manual treats the board as a
mysterious black box.)

This is kind of silly, since in principle it's just new RAMs and new ROMs,
but my recollection (from the last time I did the brain transplant) is that
the LJ and LJ+ boards are laid out somewhat differently, i.e. they may have
made other changes.

Beware that the fine print in the specs for those things often says "for
LJ+ or LJ2 only".  I assume this is because of stupid firmware in the LJ
that isn't up to handling strange-looking cartridges.
