Additional Pictures 

 

This Montgomery Ward TXI-8662A was manufactured in August 1974 by
Texas Instruments (Date code 33 4 wk 33 yr 1974).

 

The printed circuit board (PCB) of the Montgomery Ward P200
looks very familiar to us.

The PCB of the Montgomery Ward P200  is centered
around the TMS0601 single-chip calculator circuit
