#2Very cool. No surprise when I saw Ben Eater acknowledgement at the bottom. I'd humbly suggest including the CAD (KiCad?) files to go along with the gerbers.

#3The Minitel can be used as a modem too, albeit a cumbersome and very slow one: 1200bps down, 75bps up. Bps as in bits per second.
That’s how I connected to bbses and nntp before I finally got a 2400bps real modem.
Nice project, and how far we’ve come !

Some younger folks seem to be into all sorts of classic tech these days, like vynil, mechanical keyboards and terminal emulators. But I'm yet to see people giving old modems are try... Probably because there is nothing waiting for them to call anymore :(.
(telnet doesn't count)

Not just that, but, as I understand it, with some of the modern digital phone systems, they won’t work properly even if you did have someplace to call.
And 2400 baud was quite useful for a personal NNTP feed.

IIRC the Minitel had a TTL level serial port that’d work at 4800 bps.

#7Building a 6502 computer from scratch is cool enough on its own, but hooking it up to a Minitel terminal takes it to a whole new level! Outstanding work.

9600 even! :)

Computer to Minitel ttl yes.
However the modem part was limited to those paltry figures.
I still have mine in the basement. Maybe its capacitors are all busted…time to give it a spin !
