So, yeah, that isn't particularly common. But 10 V is. Unfortunately I don't know how sensitive they are to the voltage. Most machines would be fine with 10V instead of 10.5, but a turbografx CD isn't exactly typical. I'd be tempted to modify the cord of a 10V sega genesis adapter and use that, but probably should do more research.
edit: crap, the above specs are for the TurboGrafx 16 power supply, not the CD. Been a long time since I used the CD, and now I have no idea how I powered it.
