Commodore Bildschirmtext II Decoder Cartridge #Commodore #Gaming #ReverseEngineering @pagetable
Thanks to pagetable.com, here are some pictures of the outside and the inside of a Commodore Bildschirmtext II Decoder Cartridge for the C64 – a 6800-based computer connected to the expansion port!
Bildschirmtext (Btx) was a German online service that existed from 1983 to 2001. To use the service with a C64, this decoder cartridge was required, which connected to the expansion port.
The board reveals that the cartridge doesn’t only have its own video chip, it also has its own CPU, RAM and ROM – it’s a complete computer that only connects to the C64 in order to reuse the keyboard and the disk drive.
