Project Info

Some works has been undertaken with this module. I downloaded and analyzed software which is typical SIEMENS Teletext soft. Already exchanged DIP28 socket for DIP32 socket flash and rerouted additional address paths, so now my software can be tested.

Unfortunatelly there is no programming manual for SDA5450 which is bigger version of SDA5250. Analyzing software I can see similiar things to HF-1774 and HF-17831.

Development plans

As for all teletext related modules and uCs I thinking about custom graphic card/system based on teletext.
