For Sale TI-99/4A Finalgrom99 cartridge and 32k ram sidecart expansion

[HomeLate]

Update 22/09/2025: all Finalgrom99's are sold. If there's enough interest, then I will order more PCB's. Note, the CLPD XC95144XL-10TQ100 is marked EOL by AMD and no longer manufactured.


I was recently asked to build a Finalgrom99 and 32k sidecart ram expansion for the TI-99/4A.

Besides from building one for a friend and myself, I have three one none PCB of the FinalGrom left of each and parts available to build one immediately. I have to order the parts for one more.

The Finalgrom is a cartridge which allows you to load rom images from an SD-card. As the cartridge can run on a standard TI-99/4A, some roms need 32k to run, hence the need for the 32k ram sidecart expension which plugs in on the side of your TI-99/4A. The PCB's are made with ENIG finish and the Finalgrom99's PCB has gold fingers. The Finalgrom99 is not compatible with the TI-99/4A Qi machines.

Each come in a black 3d printed case, a SD-card is not included. One can ship immediately, I need to order parts for the two remaining PCB's which takes roughly a few days to arrive.

Pricing:

- Finalgrom99: 65 euro with 3d-printed case included
- 32k sidecart ram expansion: 39 euro

Contact me for shipping details

Edit: Final Finalgrom99 is sold to Bartek2075.
