Actually the 38G was a spin-off from the HP 48G series, and uses the green/blue G series LCD;-)

Internally, the 38G OS is more advanced than that of the 48G series, as it introduced the Topic Outer Loop (TOL) around the normal Parameterized Outer Loop (POL), which allows kinda cooperative task switching. OTOH the 38G is a closed platform, with the underlying RPL OS well hidden from the user, and therefore not interesting for me.
The slide-on protective cover is nice, though.
