    I have now purchased four items from this fellow; all still work perfectly and are used in functioning retro systems used often. Not just gaming, learning packages as the all four items are for the venerable TI 99/4a system - allowing for 32k memory expansion and FinalGrom99 usage - (different cartridge selection) upon soft reboot of the computer -- instead of having to power down the TI and physically change cartridges. 32k memory expansion unit is compatible to 44-pin TIPI expansion boards. A+

    Shipped quickly, Decent build quality with the 3d print. The cartridge does slot into the TI99/4A very nicely. My only issue is that the Finalgrom99 board can move a bit when trying to remove and insert the SD card.

    Very good quality, real nice 3D-Printed-Cartridge. Fully functional as described on Github. I've copied some ROM-Files (there is a complete collection for the FinalGROM99 that can be found on the internet) to a FAT32 formated 4GB SD-Card and I was able to travel back in time and played my favorite games from the early 80ies. Great product to get software easily to a TI99/4a. Top seller.
