TI-99/4A FAQ: Monitor and TV hookups

How do I hook up my TI to a modern tv/monitor?

The TI-99/4A NTSC model released in the USA and other countries supports a standard 5 pin DIN connector.  Many 8 bit computers of the era all share the same cable, Atari 800, ColecoVision, Coleco Adam, C64 are some examples.

The TI-99/4A PAL model relased in Europe and other PAL countries supports a 7 pin DIN connector.

      • For those interested in getting a F18A VGA VDP replacement for your TI-99/4a here’s the latest status and updates:  https://dnotq.io/f18a/f18a.html
      • I periodically have these in stock:
    • VGA to HDMI adapters have been used to make this work with HDMI only displays. http://atariage.com/forums/topic/234226-hdmi-for-the-ti/ I have these in my store at arcadeshopper.com
    • The audio is still output through the 5pin DIN video port so you will still need a composite cable with at least the audio pins connected to a speaker if you install a F18A you can buy these at arcadeshopper.com
