**Busicom 141 Desktop Calculator**

NCM/Busicom 141

The Busicom 141 was a follow-on to Nippon Calculating Machine Co., Ltd.'s first desktop electronic calculator, the Busicom 161. The 141 was a somewhat stripped-down version of the 161, providing 14 digits of capacity versus 16 of the 161, and omitting the square root function. The machine utilizes all discrete diode/transistor logic, along with a 256-bit magnetic core memory array for working register storage. The calculator operates with fixed decimal point for all operations, selected at 0, 1, 2, 3, 6 or 8 digits behind the decimal point. Like the 161, the machine provides a 'backspace' feature for error correction, along with true credit balance.
