CD-i 18x power question

Does anyone here know if a CDI 18x/37 set (US version) which is rated for 120V / 60Hz can handle the 220V / 50Hz power produced by most converters?

I found out that it does indeed work. Now I need to find a working CDI 180 pointing device, standard peripherals unfortunately don't work...

Here's a nice picture...
I'm using a cheap 100W power converter (€19,95); it works fine.
Edit: If you want more photos, look
here, it's the same set.

Looking good, I'm glad it's all up and running and arrived in one piece for you

It's running, yeah, but I can't do much with the physical thing.
I haven't got a working pointing device (yet) and without that I cannot click "CD-I" to get a disc playing. There's also no serial port. I've thought of ways to remedy both, though.
Shameless plug: Details on my blog tonight!

Can we get a link to the blog?
(Sorry if I've missed it)

I think I only have one mouse and remote control, but I do have an extra serial port for the cdi180. IIRC the serial port is just a connector on a PCB which plugs into the machine, no logic. I also have the third authoring module.

That's what I suspected, and today I confirmed it. The serial port is indeed just a connector.
I found a pair of 75188/75189 chips on the print (RS232 line drivers/receivers) and with my multimeter I traced the serial I/O signals from the 68070 through these chips and a resistor to the PCB card edge connector. I know even the pins.
Edit: Much more about CD-i 180 internals is described in the new article on my
CD-i Bits blog.
