MSX Service/Repair Manual

Hi folks ! Just found this site through Ask Jeeves and I wonder if anyone can help me. I recently came across a Toshiba HX-10 MSX machine, fully boxed for £3. However it is not working and I would like to know if there are any service or repair manuals available on the net. I'm fairly knowledgable of electronics and would hopefully like to carry out a repair myself with the right info. I'm quite fascinated with the MSX. I remember about 15 years ago a friend of my having one but never having a good play with it. I recently came across MSX emulators, but now I have a real one I would like to get it working. Any help would be great. Cheers !
