"Little Brother" machine to the NCR 18-2, and NCR 18-3 calculators,
introduced slightly later than these two earlier machines. 14-digits Burroughs Panaplex-style seven-segment display, with "half-sized" zeroes for leading zero display. One accumulating
memory register. Four function, with fixed decimal point settings. Utilizes
small-scale integrated circuits, along with a small magnetic core memory plane for register storage. This machine also appears to be manufactured by Nippon Calculating Machine Co. (Busicom), and sold under OEM license by NCR. At this point in time, the model number of the corresponding Busicom machine is not known.
