Chess for the TI on the web

01/31/16 - I have released the first version of Chess, which you can play agains others on the web with your TI. Once I heard about Stuart Conner's web browser, I knew I had to try to make some cool games for it. Chess is my first one and I have a few ideas for others. This version of chess is still in development, and may have bugs. Please let me know if you find any.

I'd also like to point out that as of right now:

  • There is no Castling ability yet.
  • There is no En Passant support yet. It's just plain chess, as I remember playing it as a kid. If you're interested in playing against other TI retronauts, read on.

    To play Chess for the TI on the web, you must have the following:
  • A TI 99/4A console
  • 32K memory expansion
  • A RS232 interface. Both the PEB card and NanoPEB v1 have been tested
  • A copy of Stuart Conner's web browser for the TI, v8.2 or newer Available Here
  • A account, which you can create here for free

    To play chess:
    Once you have registered for a account, go to this address on your TI console:
    From there you'll be able to browse for open games, or create one yourself. You can play up to 5 simultaneous matches.

    You can save this URL to your favorites for future retrieval. The browser doesn't support text input at this time, and does not (yet) support cookies.
    This makes "logging in" a little less secure than a traditional system, and you must log in by adding your
    screen name to the URL. For example screen name: TI99FAN you would enter this into the browser:

    You can then use your PIN to complete the login process via the PIN pad by clicking on the numbers.
    You can also enter all of this information on the URL. For example if your PIN was 1234:

    This will log all the way in and bypass the tedious PIN pad.

    UPDATE: Stuart's browser v9 and greater supports text input, and I have created a login page on

    Check back often as I will be updating this site over the coming weeks.
