Viditel / Presetel prototype cartridge - hofster - 04-13-2020 Hi, I found a prototype cartridge for the TI-99. The cartridge is labelled Viditel although it has programs called Prestel and Bildshirmtext on it too (same thing in different languages perhaps). I wonder if anyone has any more knowledge about this little gem. I posted my findings here: https://perhof.wordpress.com/2020/04/13/ti-99-viditel-cartridge/
