Minitel 2
The Minitel is a small, on-line computer/Videotex terminal with multi-services that
can be connected to any French telephone line. This terminal was widely used in France
during the 80's and 90's.
There are several models and versions. Most of them are based on 8051 compatible MCUs
and EF9345 semi graphic video chip.
The current implementation is a Minitel 2 from "La RADIOTECHNIQUE PORTENSEIGNE" / RPIC (Philips)
More Minitel hardware related informations are available on this page :
http://hxc2001.free.fr/minitel
What is implemented and working :
- Main MCU
- Video output
- Keyboard
- 24C02 EPROM
- Modem serial interface.
What is implemented but not working :
- The rear serial port.(Prise péri-informatique)
(Internal 8051 serial port emulation missing).
What is not yet implemented :
- Sound output.
- Screen should go blank when switched off
The original firmware and the experimental demo ROM are currently both working.
Please note the current special function keys assignation :
F1 -> Suite
F2 -> Retour
F3 -> Envoi
F4 -> Repetition
F5 -> TEL
F6 -> Guide
F7 -> Sommaire
F8 -> Connexion/Fin
F10-> ON / OFF
Alt Gr -> Fonction
With the official ROM you need to press F10 to switch on the CRT.
Modem and external port can be exported to the "modem" and "periinfo"
interfaces.
Example : Command line options to use to create a TCP socket linked to
the modem port : "-modem null_modem -bitb socket.127.0.0.1:20000"
Once mame started you can then send vdt files with netcat to this socket.
