Hi all, I made a try and installed OVMS 8.3 under the DS10 emulator PersonalAlpha+ (Stromasys) on a PC powered with a intel CoreI5 3 Ghz. The Vup rating is about 46 Vups (I mesure 425 on my DS15A 1 Ghz), which is very usable (I even managed to run Xboing successfully). The commercial version claimed to be 5 times faster, have you tried ? Patrick
