Toshiba is rumored to have manufactured a MSX turboR-like computer for medical purposes a few years ago. But no confirmation whatsoever was ever given. So this may just be what it is, a rumor.
Here's 3 pics (found on the net) of the Toshiba HX-10. It's a funny MSX to look at and although it has 64kB RAM, it's hardly spectacular.
Sorry, currently no pics of Toshiba MSX2's...
