What is TIPI?

TIPI is a storage, network, and device solution expansion for the TI-99/4A home computer.

There is some community driven support for the Myarc Geneve 9640 Family Computer. I do not own one, and so my ability and interest in contributing is limited.


  • J-Data's combined TIPI/32K - specific info:
  • sideport model is available requiring a Jedimatt42 style 32k adapter, or something with equivalent header connector such as the sideport SAMS memory adapter
  • Peripheral Expansion Box board is available, called TipiPEB
  • Emulation support is available : Emulation Installation

Getting Started (Start Here!!!)

Atariage Development Thread


It is unlikely that I built your hardware. If you suspect hardware issues, reaching out to the supplier directly or use the official support thread I created on Atariage:

Atariage Support Thread

Most of the hardware vendors monitor this thread, along with other users, and myself who can help with troubleshooting advice.

For software support - the TIPI DSR, Raspberry PI software, update, and configuration tools, I ask that you reach out to that Atariage support thread above.

Where to buy

If you think maintenance of the TIPI software is a worthwhile endeaver, consider voting with your dollars at:

I participated in the hand crafting of maybe the first 60 pieces to recover material investments during development. After that, since about 2018, I haven't participated in the manufacturing and supply other than volunteering to troubleshoot and repair poorly made boards as a favor to ArcadeShopper and the community.

Buy assembled hardware and kits at ArcadeShopper

You must still provide your own Raspberry PI 3/3+ or Zero W, micro-sd card, and 2.5amp or greater power supply to the Raspberry PI.

To build it yourself

Requires a Xilinx CPLD programming cable, eprom programmer, a place to print pcboards, and sourcing parts. The design files are in github under the hardware folder for the project. They are in KiCad format. You should install KiCad, so you can produce gerbers, and review the schematic and pcboard layout as well as the parts mapping for the BOM. I source most parts from DigiKey, Jameco, and ebay.
