And you can use some of them as a serial console using a simple TTL to serial voltage adapter.
The following are compatible with 80 columns:
Minitel 1B
Minitel 2
And type the following after power on to switch to 80 cols:
Function T+E

Use online translator and ping me if needed.
We use 50hz too.
I thought about doing it this way, but was rather planning to do it slightly differently, by building the right modulator (at, what was it? 2600 bauds? it should be pretty doable to bit-bang using an arduino, or the RPI's GPIO. Maybe even with a digital output, though I'm thinking of using a DAC. Or hell, if using a raspberrypi, why not the audio or video output?
Another option is to bypass the motherboard and use the CRT + keyboard. A friend of mine plans to do just that, and I saw someone post this link on your blog: http://www.cfp-radio.com/realisations/rea48/minitel-01.html
Well, that's for the plans... It's pretty unlikely I'll start this project before 6 months, as I have a lot on my plate :/
