Elektor published in 1978 the Elekterminal design: a video display unit and an ASCII keyboard for computer systems with serial interface.
Over the years the design evolved and many articles were published. Among other systems, it was also integrated with the Junior computer.
The Juinor book 3 contains a detailed description how to combine Elekterminal and Junior via the bit banged serial TTY interface.
The video display was later replaced with a videocard, the serial ASCI keyboard stayed as option.
