The system needs two flavors of voltage in one plug, gives the voltage and polarity but no pinout. Anyone have one or know?
There is someone saturday at the msx day in Nijmegen, he asks who wants to buy a HB-10. Maybe he knows ? I cant go sadly, school is important. http://www.msx.org/forum/msx-talk/trading-and-collecting/lots-msx-hardware-sale-nijmegen-2012
I have an Yamaha MSX that came out the same year as yours and the power supply is quite complex and bulky. I think your best bet is to ask the Dutch, Spanish or French community, MSX had a massive following there. Try www.msx.org there's a page on connectors here as well.
