Vintage Texas Instruments TM 990/189 Microcomputer, Used, working

The device is programmable from the calculator that is attached to the board, or optionally there are pads on the circuit board for connecting a serial port. This is a rare collectible due to its unusual combination of computer development kit and calculator user interface.

The device powers up and says "CPU Ready", which is what is supposed to do. I have also verified that the keypad works and that you can enter a string.

I have not done any additional testing, so please keep that in mind. The item "Vintage Texas Instruments TM 990/189 Microcomputer, Used, working" is in sale since Saturday, August 18, 2018.
