Welcome to the TIPI/32K Wiki!

This Wiki covers items specific to the TIPI/32K version of the TIPI. For general help common to all versions of the TIPI, please see Jedimatt42's TIPI wiki.

What is TIPI/32K?


TIPI/32k is a derivative of the original TIPI designed by Jedimatt42 and ElectricLab, but modified to fit in the TI-99/4A speech synthesizer housing. It combines both the sideport TIPI and the sideport 32K memory expansion into a single PCB. The primary goals of this version are to:

  • Make a smaller, simpler package for the TIPI, matching the original factory TI-99/4 look and feel.
  • Reduce cost by integrating the TIPI and 32K cards, using the Pi ZeroW, and designing for low cost production and simple assembly.
  • Getting more TIPIs in the hands of us casual TI-99/4A users.
  • Finally finding a use for that door on the speech synthesizer housing.
  • Have some fun with a TIPI PCB design.
