Luke also shared a very interesting story behind the Viditel software and a plausible background to my cartridge in a comment at my blog. https://perhof.wordpress.com/2020/04/13/ti-99-viditel-cartridge/

I don't know how to setup a connection through a wifimodem but there seems to be a Prestel compatible (same protocol as Viditel as I understand it) server at glastty.com:6502 https://glasstty.com/wiki/index.php/The_TELSTAR_Videotex_System

Nice. Thanks for trying it out. I see that you got further than me. Is that because you have a serial port available or did you even have a modem?

Sweet! Are you running it from a cartridge or from a disk? Where did you get it from?

Hi, New user here since i never was a TI-99 user myself... I have recently found a Viditel / Prestel / Bildschirmtext prototype cartridge that I would like to know more about. I have dumped the ROM and and made a short write-up and posted some pictures of it here: https://perhof.wordpress.com/2020/04/13/ti-99-viditel-cartridge/ I hope anyone could tell me more about that little gem.
