MiniWriter 3 cart (with novel, integrated parallel interface)
This thing is pretty interesting.

Does anyone have a photo of this cracked open? Id love to see how its pit together. Can the TI write (output) to the cart port? Hmmm....trying to recall if MiniMemory is a command module or a side attach cart. Maybe the whole bus is exposed on that cart connector.
Im intrigued.
I made one. It works! Since I only had IDC connections, I had to use a PCB to bridge the connections, as they go in a different order on the IDC Centronics connector. (1, 19, 2, 20, etc).
Note that pin 1 on the edge connector is on the right side of the Miniwriter cart.
Also note the ribbon on the Centronics side is backward. Pin 1 is not the red stripe. Oh well.
